Product Description
ACTIVE-POWER INDUSTRIES Angular Contact Ball Bearing 7007C China Factory 7319BM Double Row Angular Contact Ball Bearing
Product Description
The connection line between the steel ball of the contact ball bearing and the contact point of the inner and outer rings forms an angle with the radial direction. Contact angles are generally divided into 15°, 30°, and 40°, which are represented by letters C, A, and B respectively.
Angular contact ball bearings mainly bear large unidirectional axial loads, and the larger the contact angle, the greater the load-bearing capacity. The material of the cage is steel plate, brass, or engineering plastic, and the forming method is stamping or turning, which is selected according to the bearing form or service conditions. Others include combined angular contact ball bearings, double-row angular contact ball bearings, and four-point contact ball bearings.
Angular contact ball bearings can bear radial load and axial load at the same time. Can work at higher speeds. The larger the contact angle, the higher the axial load-carrying capacity. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase. Single-row angular contact ball bearings can only bear axial load in 1 direction and will cause additional axial force when bearing radial load. And it can only limit the axial displacement of the shaft or housing in 1 direction. If it is installed in pairs, make the outer rings of a pair of bearings face each other, that is, the wide end faces the wide end face, and the narrow end faces the narrow end face. This avoids causing additional axial forces and limits the shaft or housing to axial play in both directions.
Because the raceway of the inner and outer rings of the angular contact ball bearing can have relative displacement on the horizontal axis, it can bear radial load and axial load at the same time – combined load (single row angular contact ball bearing can only bear axial load in 1 direction, Therefore, they are generally installed in pairs). The material of the cage includes brass, synthetic resin, etc., which are distinguished according to the bearing type and service conditions.

How does Preload Affect the Performance and Efficiency of Ball Bearings?
Preload is a crucial factor in ball bearing design that significantly impacts the performance, efficiency, and overall behavior of the bearings in various applications. Preload refers to the intentional axial force applied to the bearing’s rolling elements before it is mounted. This force eliminates internal clearance and creates contact between the rolling elements and the raceways. Here’s how preload affects ball bearing performance:
- Reduction of Internal Clearance:
Applying preload reduces the internal clearance between the rolling elements and the raceways. This eliminates play within the bearing, ensuring that the rolling elements are in constant contact with the raceways. This reduced internal clearance enhances precision and reduces vibrations during operation.
- Increased Stiffness:
Preloaded bearings are stiffer due to the elimination of internal clearance. This increased stiffness improves the bearing’s ability to handle axial and radial loads with higher accuracy and minimal deflection.
- Minimized Axial Play:
Preload minimizes or eliminates axial play within the bearing. This is especially important in applications where axial movement needs to be minimized, such as machine tool spindles and precision instruments.
- Enhanced Rigidity:
The stiffness resulting from preload enhances the bearing’s rigidity, making it less susceptible to deformation under load. This is critical for maintaining precision and accuracy in applications that require minimal deflection.
- Reduction in Ball Slippage:
Preload reduces the likelihood of ball slippage within the bearing, ensuring consistent contact between the rolling elements and the raceways. This leads to improved efficiency and better load distribution.
- Improved Running Accuracy:
Preloading enhances the running accuracy of the bearing, ensuring that it maintains precise rotational characteristics even under varying loads and speeds. This is essential for applications requiring high accuracy and repeatability.
- Optimized Performance at High Speeds:
Preload helps prevent skidding and slipping of the rolling elements during high-speed operation. This ensures that the bearing remains stable, reducing the risk of noise, vibration, and premature wear.
- Impact on Friction and Heat Generation:
While preload reduces internal clearance and friction, excessive preload can lead to higher friction and increased heat generation. A balance must be struck between optimal preload and minimizing friction-related issues.
- Application-Specific Considerations:
The appropriate amount of preload depends on the application’s requirements, such as load, speed, accuracy, and operating conditions. Over-preloading can lead to increased stress and premature bearing failure, while under-preloading may result in inadequate rigidity and reduced performance.
Overall, preload plays a critical role in optimizing the performance, accuracy, and efficiency of ball bearings. Engineers must carefully determine the right preload level for their specific applications to achieve the desired performance characteristics and avoid potential issues related to overloading or inadequate rigidity.

What are the Challenges Associated with Noise Reduction in Ball Bearings?
Noise reduction in ball bearings is a crucial consideration, especially in applications where noise levels must be minimized for operational efficiency and user comfort. While ball bearings are designed to operate smoothly, there are several challenges associated with reducing noise in their operation:
- Vibration:
Vibration generated by the movement of rolling elements and raceways can lead to noise. Even minor irregularities in bearing components or the mounting system can cause vibration that translates into audible noise.
- Bearing Type and Design:
The type and design of the ball bearing can impact noise generation. For example, deep groove ball bearings are known for their quiet operation, while angular contact bearings can generate more noise due to their higher contact angles.
- Lubrication:
Improper or inadequate lubrication can result in increased friction and wear, leading to noise. Choosing the right lubricant and maintaining proper lubrication levels are essential for reducing noise in ball bearings.
- Bearing Clearance and Preload:
Incorrect clearance or preload settings can lead to noise issues. Excessive clearance or inadequate preload can cause the rolling elements to impact the raceways, resulting in noise during rotation.
- Material and Manufacturing Quality:
The quality of materials and manufacturing processes can affect noise levels. Inconsistent or low-quality materials, improper heat treatment, or manufacturing defects can lead to noise generation during operation.
- Surface Finish:
The surface finish of the rolling elements and raceways can impact noise. Rough surfaces can generate more noise due to increased friction and potential irregularities.
- Sealing and Shielding:
Seals and shields that protect bearings can influence noise levels. While they are necessary for contamination prevention, they can also cause additional friction and generate noise.
- Operating Conditions:
External factors such as temperature, speed, and load can influence noise levels. High speeds or heavy loads can amplify noise due to increased stress on the bearing components.
- Wear and Deterioration:
As ball bearings wear over time, noise levels can increase. Worn components or inadequate lubrication can lead to more significant noise issues as the bearing operates.
To address these challenges and reduce noise in ball bearings, manufacturers and engineers employ various techniques, such as optimizing design, selecting suitable bearing types, using proper lubrication, maintaining accurate preload settings, and ensuring high-quality materials and manufacturing processes. Noise reduction efforts are essential to improve overall product quality, meet noise regulations, and enhance user experience in various applications.
What are the Differences between Deep Groove Ball Bearings and Angular Contact Ball Bearings?
Deep groove ball bearings and angular contact ball bearings are two common types of ball bearings, each designed for specific applications and load conditions. Here are the key differences between these two types of bearings:
- Design and Geometry:
Deep Groove Ball Bearings:
Deep groove ball bearings have a simple design with a single row of balls that run along deep raceways in both the inner and outer rings. The rings are usually symmetrical and non-separable, resulting in a balanced load distribution.
Angular Contact Ball Bearings:
Angular contact ball bearings have a more complex design with two rows of balls, oriented at an angle to the bearing’s axis. This arrangement allows for the transmission of both radial and axial loads, making them suitable for combined loads and applications requiring high precision.
- Load Carrying Capacity:
Deep Groove Ball Bearings:
Deep groove ball bearings are primarily designed to carry radial loads. They can handle axial loads in both directions, but their axial load-carrying capacity is generally lower compared to angular contact ball bearings.
Angular Contact Ball Bearings:
Angular contact ball bearings are specifically designed to handle both radial and axial loads. The contact angle between the rows of balls determines the bearings’ axial load-carrying capacity. They can handle higher axial loads and are commonly used in applications with thrust loads.
- Contact Angle:
Deep Groove Ball Bearings:
Deep groove ball bearings have no defined contact angle, as the balls move in a deep groove along the raceways. They are primarily designed for radial loads.
Angular Contact Ball Bearings:
Angular contact ball bearings have a specified contact angle between the rows of balls. This contact angle allows them to carry both radial and axial loads and is crucial for their ability to handle combined loads.
- Applications:
Deep Groove Ball Bearings:
Deep groove ball bearings are commonly used in applications that primarily require radial loads, such as electric motors, pumps, and conveyor systems. They are also suitable for high-speed operation.
Angular Contact Ball Bearings:
Angular contact ball bearings are used in applications where both radial and axial loads are present, such as in machine tools, automotive wheel hubs, and aerospace components. They are especially useful for applications that require precise axial positioning and handling of thrust loads.
- Limitations:
Deep Groove Ball Bearings:
Deep groove ball bearings are not as suitable for handling significant axial loads and may experience skidding under certain conditions due to their deep raceways.
Angular Contact Ball Bearings:
Angular contact ball bearings can experience increased heat generation and wear at higher speeds due to the contact angle of the balls.
In summary, the design, load-carrying capacity, contact angle, and applications differ between deep groove ball bearings and angular contact ball bearings. Choosing the appropriate type depends on the specific load conditions and requirements of the application.
What are the Different Components that Make up a Typical Ball Bearing?
A typical ball bearing consists of several essential components that work together to reduce friction and support loads. Here are the main components that make up a ball bearing:
- Outer Ring:
The outer ring is the stationary part of the bearing that provides support and houses the other components. It contains raceways (grooves) that guide the balls’ movement.
- Inner Ring:
The inner ring is the rotating part of the bearing that attaches to the shaft. It also contains raceways that correspond to those on the outer ring, allowing the balls to roll smoothly.
- Balls:
The spherical balls are the rolling elements that reduce friction between the inner and outer rings. Their smooth rolling motion enables efficient movement and load distribution.
- Cage or Retainer:
The cage, also known as the retainer, maintains a consistent spacing between the balls. It prevents the balls from touching each other, reducing friction and preventing jamming.
- Seals and Shields:
Many ball bearings include seals or shields to protect the internal components from contaminants and retain lubrication. Seals provide better protection against contaminants, while shields offer less resistance to rotation.
- Lubricant:
Lubrication is essential to reduce friction, wear, and heat generation. Bearings are typically filled with lubricants that ensure smooth movement between the balls and raceways.
- Flanges and Snap Rings:
In some designs, flanges or snap rings are added to help position and secure the bearing in its housing or on the shaft. Flanges prevent axial movement, while snap rings secure the bearing radially.
- Raceways:
Raceways are the grooved tracks on the inner and outer rings where the balls roll. The shape and design of the raceways influence the bearing’s load-carrying capacity and performance.
- Anti-Friction Shield:
In certain high-speed applications, a thin anti-friction shield can be placed between the inner and outer rings to minimize friction and heat generation.
These components work together to enable the smooth rolling motion, load support, and reduced friction that characterize ball bearings. The proper design and assembly of these components ensure the bearing’s optimal performance and longevity in various applications.

How does Preload Affect the Performance and Efficiency of Ball Bearings?
Preload is a crucial factor in ball bearing design that significantly impacts the performance, efficiency, and overall behavior of the bearings in various applications. Preload refers to the intentional axial force applied to the bearing’s rolling elements before it is mounted. This force eliminates internal clearance and creates contact between the rolling elements and the raceways. Here’s how preload affects ball bearing performance:
- Reduction of Internal Clearance:
Applying preload reduces the internal clearance between the rolling elements and the raceways. This eliminates play within the bearing, ensuring that the rolling elements are in constant contact with the raceways. This reduced internal clearance enhances precision and reduces vibrations during operation.
- Increased Stiffness:
Preloaded bearings are stiffer due to the elimination of internal clearance. This increased stiffness improves the bearing’s ability to handle axial and radial loads with higher accuracy and minimal deflection.
- Minimized Axial Play:
Preload minimizes or eliminates axial play within the bearing. This is especially important in applications where axial movement needs to be minimized, such as machine tool spindles and precision instruments.
- Enhanced Rigidity:
The stiffness resulting from preload enhances the bearing’s rigidity, making it less susceptible to deformation under load. This is critical for maintaining precision and accuracy in applications that require minimal deflection.
- Reduction in Ball Slippage:
Preload reduces the likelihood of ball slippage within the bearing, ensuring consistent contact between the rolling elements and the raceways. This leads to improved efficiency and better load distribution.
- Improved Running Accuracy:
Preloading enhances the running accuracy of the bearing, ensuring that it maintains precise rotational characteristics even under varying loads and speeds. This is essential for applications requiring high accuracy and repeatability.
- Optimized Performance at High Speeds:
Preload helps prevent skidding and slipping of the rolling elements during high-speed operation. This ensures that the bearing remains stable, reducing the risk of noise, vibration, and premature wear.
- Impact on Friction and Heat Generation:
While preload reduces internal clearance and friction, excessive preload can lead to higher friction and increased heat generation. A balance must be struck between optimal preload and minimizing friction-related issues.
- Application-Specific Considerations:
The appropriate amount of preload depends on the application’s requirements, such as load, speed, accuracy, and operating conditions. Over-preloading can lead to increased stress and premature bearing failure, while under-preloading may result in inadequate rigidity and reduced performance.
Overall, preload plays a critical role in optimizing the performance, accuracy, and efficiency of ball bearings. Engineers must carefully determine the right preload level for their specific applications to achieve the desired performance characteristics and avoid potential issues related to overloading or inadequate rigidity.

Are there Specific Maintenance Practices to Ensure the Longevity of Ball Bearings?Maintaining ball bearings is essential to ensure their longevity, reliable performance, and prevent premature failure. Proper maintenance practices can extend the lifespan of ball bearings and the equipment they are used in. Here are specific maintenance practices to consider:
Implement a regular lubrication schedule using the appropriate lubricant for the application. Lubrication reduces friction, prevents wear, and helps dissipate heat. Follow manufacturer guidelines for lubricant type, quantity, and frequency.
Keep the operating environment clean and free from contaminants. Dust, dirt, and debris can infiltrate bearings and cause damage. Use seals or shields to protect bearings from contaminants, especially in harsh environments.
Ensure correct installation of bearings using proper tools and techniques. Improper installation can lead to misalignment, uneven load distribution, and premature wear. Follow manufacturer recommendations for installation procedures.
Perform routine visual inspections to check for signs of wear, damage, or contamination. Regular inspections can help identify issues early and prevent further damage. Pay attention to noise, vibration, and temperature changes.
Monitor bearing temperatures during operation using infrared thermometers or sensors. Abnormal temperature increases can indicate inadequate lubrication, misalignment, or other problems.
Handle bearings with care to prevent damage during storage, transportation, and installation. Avoid dropping or subjecting them to impacts that can affect their internal components.
Follow proper procedures when removing and replacing bearings. Use appropriate tools and techniques to avoid damage to the bearing or the surrounding components.
Maintain proper shaft and housing alignment to prevent excessive loads and wear on the bearing. Misalignment can lead to increased stress and premature failure.
Provide training to operators and maintenance personnel on proper bearing maintenance and handling practices. Educated personnel are more likely to identify issues and perform maintenance correctly.
Keep records of maintenance activities, inspections, lubrication schedules, and any issues encountered. This documentation helps track the bearing’s performance over time and informs future maintenance decisions. By implementing these maintenance practices, you can ensure the longevity of ball bearings, minimize downtime, reduce operational costs, and maintain the reliability of the equipment they are a part of.
What Precautions should be taken to Prevent Contamination of Ball Bearings in Industrial Settings?Preventing contamination of ball bearings is essential to ensure their proper function, longevity, and overall performance in industrial settings. Contaminants such as dust, dirt, debris, and particles can significantly impact bearing operation. Here are important precautions to take to prevent contamination of ball bearings:
Choose ball bearings with appropriate seals or shields to prevent the ingress of contaminants. Seals provide a physical barrier against dust, moisture, and particles, ensuring the bearing’s interior remains clean.
Maintain a clean working environment around the machinery and equipment. Regularly clean the surrounding areas to prevent the accumulation of dirt and debris that could enter the bearings.
Handle bearings with clean hands and use gloves if necessary. Avoid touching the bearing surfaces with bare hands, as natural skin oils can transfer contaminants onto the bearing.
Use clean tools and equipment during installation and maintenance to prevent introducing contaminants. Ensure that tools are properly cleaned before coming into contact with the bearing components.
Establish contamination-controlled workstations for bearing handling, installation, and maintenance. These areas should have proper ventilation, filtered air, and minimal exposure to external contaminants.
Use the correct lubricant in appropriate quantities. Lubricants help create a barrier against contaminants and reduce friction. Regularly inspect and replenish lubrication to maintain its effectiveness.
Implement a routine inspection schedule to monitor the condition of the bearings. Look for signs of contamination, wear, and damage. Address any issues promptly to prevent further damage.
Train personnel on proper handling, installation, and maintenance practices to minimize the risk of contamination. Educated employees are more likely to take precautions and prevent accidental contamination.
In sensitive environments, such as clean rooms or medical facilities, implement strict environmental controls to minimize the presence of contaminants that could affect bearing performance.
Perform regular cleaning and maintenance of machinery and equipment to prevent the buildup of contaminants. Keep bearings protected during maintenance to prevent debris from entering during the process.
Choose bearings that are specifically designed for the application’s environmental conditions. Some bearings have advanced sealing options or specialized coatings that enhance contamination resistance. By implementing these precautions, industries can significantly reduce the risk of contamination in ball bearings, ensuring smooth operation, extended bearing life, and enhanced equipment reliability.
What Factors should be Considered when Selecting a Ball Bearing for a Particular Application?Selecting the right ball bearing for a specific application involves careful consideration of various factors to ensure optimal performance, longevity, and reliability. Here are the key factors that should be taken into account:
Determine the type of load (radial, axial, or combined) and the magnitude of the load that the bearing will need to support. Choose a bearing with the appropriate load-carrying capacity to ensure reliable operation.
Consider the rotational speed of the application and the operating conditions, such as temperature, humidity, and exposure to contaminants. Different bearing types and materials are suited for varying speeds and environments.
For applications requiring high accuracy and precision, such as machine tool spindles or optical instruments, choose high-precision bearings that can maintain tight tolerances and minimize runout.
If the application has limited space, choose miniature or compact ball bearings that can fit within the available dimensions without compromising performance.
Determine whether the application requires predominantly thrust or radial load support. Choose the appropriate type of ball bearing (thrust, radial, or angular contact) based on the primary load direction.
If the application experiences misalignment between the shaft and housing, consider self-aligning ball bearings that can accommodate angular misalignment.
Consider the ease of mounting and dismounting the bearing. Some applications may benefit from features like flanges or snap rings for secure installation.
Choose a bearing with appropriate lubrication options based on the application’s speed and temperature range. Consider whether seals or shields are necessary to protect the bearing from contaminants.
Factor in the operating environment, including exposure to corrosive substances, chemicals, water, or dust. Choose materials and coatings that can withstand the specific environmental challenges.
Select a bearing material that suits the application’s requirements. Common materials include stainless steel for corrosion resistance and high-carbon chrome steel for general applications.
Consider whether a single-row, double-row, or multiple bearings in a specific arrangement are needed to accommodate the loads and moments present in the application. By carefully evaluating these factors, engineers and designers can choose the most suitable ball bearing that aligns with the specific demands of the application, ensuring optimal performance, durability, and overall operational efficiency.
