Product Description

6900 series deep groove ball bearings are non-separable and require little attention or maintenance in service, capable of operating at high speeds and are widely used radial bearings. The inner and outer ring of single row deep groove ball bearings have a deep groove raceway. The bearings are mainly used to carry radial loads and a part of axial loads in 2 directions. This kind of bearing can carry much heavy axial loads after the increase of radial clearance, thus, it can take the place of high speed angular contact ball bearings.  Deep groove ball bearings have various types in structure, besides open type bearings, shields or seals at both sides can also be provided.

The bearings are the most typical rolling bearings with extensive applications. The raceways in both of the rings are in arc groove form, which can carry radial and axial load in double directions. They can be applied in situations where high-rotating speed and low noise and low vibration are required.

All kinds of motors, toys, medical equipment, electric vehicles, sports and office equipment.

Stainless steel bearings are corrosion-resistant and suitable for applications where moisture, chemicals, or exposure to harsh environments are concerns. AISI 440C offers high hardness and corrosion resistance, while AISI 304 and AISI 316 provide good corrosion resistance and are often used in food and medical industries.

  • Ceramic:

Ceramic bearings use silicon nitride (Si3N4) or zirconia (ZrO2) balls. Ceramic materials offer high stiffness, low density, and excellent resistance to corrosion and heat. Ceramic bearings are commonly used in high-speed and high-temperature applications, such as in aerospace and racing industries.

  • Plastic (Polyamide, PEEK):

Plastic bearings are lightweight and offer good corrosion resistance. Polyamide bearings are commonly used due to their low friction and wear properties. Polyether ether ketone (PEEK) bearings provide high-temperature resistance and are suitable for demanding environments.

  • Bronze:

Bronze bearings are often used in applications where self-lubrication is required. Bronze has good thermal conductivity and wear resistance. Bearings made from bronze are commonly used in machinery requiring frequent starts and stops.

  • Hybrid Bearings:

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.

How does Lubrication Impact the Performance and Lifespan of Ball Bearings?

Lubrication plays a critical role in the performance and lifespan of ball bearings. Proper lubrication ensures smooth operation, reduces friction, minimizes wear, and prevents premature failure. Here’s how lubrication impacts ball bearings:

  • Friction Reduction:

Lubrication creates a thin film between the rolling elements (balls) and the raceways of the bearing. This film reduces friction by separating the surfaces and preventing direct metal-to-metal contact. Reduced friction results in lower energy consumption, heat generation, and wear.

  • Wear Prevention:

Lubricants create a protective barrier that prevents wear and damage to the bearing’s components. Without proper lubrication, the repeated rolling and sliding of the balls against the raceways would lead to accelerated wear, surface pitting, and eventual failure.

  • Heat Dissipation:

Lubricants help dissipate heat generated during operation. The rolling elements and raceways can generate heat due to friction. Adequate lubrication carries away this heat, preventing overheating and maintaining stable operating temperatures.

  • Corrosion Resistance:

Lubrication prevents moisture and contaminants from coming into direct contact with the bearing’s surfaces. This helps protect the bearing against corrosion, rust, and the formation of debris that can compromise its performance and longevity.

  • Noise Reduction:

Lubricated ball bearings operate quietly because the lubricant cushions and dampens vibrations caused by the rolling motion. This noise reduction is crucial in applications where noise levels need to be minimized.

  • Seal Protection:

Lubricants help maintain the effectiveness of seals or shields that protect the bearing from contaminants. They create a barrier that prevents particles from entering the bearing and causing damage.

  • Improved Efficiency:

Properly lubricated ball bearings operate with reduced friction, leading to improved overall efficiency. This is especially important in applications where energy efficiency is a priority.

  • Lifespan Extension:

Effective lubrication significantly extends the lifespan of ball bearings. Bearings that are properly lubricated experience less wear, reduced fatigue, and a lower likelihood of premature failure.

  • Selection of Lubricant:

Choosing the right lubricant is essential. Factors such as speed, temperature, load, and environmental conditions influence the choice of lubricant type and viscosity. Some common lubricant options include grease and oil-based lubricants.

  • Regular Maintenance:

Regular lubrication maintenance is crucial to ensure optimal bearing performance. Bearings should be inspected and relubricated according to manufacturer recommendations and based on the application’s operating conditions.

In summary, proper lubrication is essential for the optimal performance, longevity, and reliability of ball bearings. It reduces friction, prevents wear, dissipates heat, protects against corrosion, and contributes to smooth and efficient operation in various industrial and mechanical applications.
