Product Description

Product Description

Deep groove ball bearing
Deep groove ball bearing formerly known as single row centripetal ball bearing, is the most widely used kind of rolling bearing. Its characteristics are small friction resistance, high speed, can be used to bear radial load or radial and axial combined load on the parts, can also be used to bear axial load on the parts, When it only bears radial load, the contact Angle is zero. When deep groove ball bearings have large radial clearance, they have the performance of angular contact bearings and can withstand large axial loads. The friction coefficient of deep groove ball bearings is very small, and the ultimate speed is also very high.

What are the Materials Typically Used in Manufacturing Ball Bearings and Their Advantages?

Ball bearings are manufactured using a variety of materials, each chosen for its specific properties and advantages in various applications. Here are some commonly used materials in ball bearing manufacturing and their respective benefits:

  • High-Carbon Chrome Steel (AISI 52100):

This is the most common material used for ball bearing manufacturing. It offers excellent hardness, wear resistance, and fatigue strength. High-carbon chrome steel bearings are suitable for a wide range of applications, from industrial machinery to automotive components.

  • Stainless Steel (AISI 440C, AISI 304, AISI 316):

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:

Hybrid bearings combine steel rings with ceramic balls. These bearings offer a balance between the advantages of both materials, such as improved stiffness and reduced weight. Hybrid bearings are used in applications where high speeds and low friction are essential.

  • Specialty Alloys:

For specific applications, specialty alloys may be used to meet unique requirements. For example, bearings used in extreme temperatures or corrosive environments may be made from materials like titanium or hastelloy.

  • Coated Bearings:

Bearings may also be coated with thin layers of materials like diamond-like carbon (DLC) or other coatings to enhance performance, reduce friction, and improve wear resistance.

The choice of material depends on factors such as application requirements, operating conditions, load, speed, and environmental factors. Selecting the right material is essential for ensuring optimal bearing performance, longevity, and reliability in diverse industries and 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.

Deep groove ball bearings are the most common and versatile type. They have a deep raceway that allows them to handle both radial and axial loads. They are used in a wide range of applications, including electric motors, household appliances, automotive components, and industrial machinery.

  • Angular Contact Ball Bearings:

Angular contact ball bearings have a contact angle that enables them to handle both radial and axial loads at specific angles. They are suitable for applications where combined loads or thrust loads need to be supported, such as in machine tool spindles, pumps, and agricultural equipment.

  • Self-Aligning Ball Bearings:

Self-aligning ball bearings have two rows of balls and are designed to accommodate misalignment between the shaft and the housing. They are used in applications where shaft deflection or misalignment is common, such as conveyor systems, textile machinery, and paper mills.

  • Thrust Ball Bearings:

Thrust ball bearings are designed to support axial loads in one direction. They are commonly used in applications where axial loads need to be supported, such as in automotive transmissions, steering systems, and crane hooks.

  • Single-Row vs. Double-Row Bearings:

Single-row ball bearings have a single set of balls and are suitable for moderate load and speed applications. Double-row ball bearings have two sets of balls and offer higher load-carrying capacity. Double-row designs are used in applications such as machine tool spindles and printing presses.

  • Miniature and Instrument Ball Bearings:

Miniature ball bearings are smaller in size and are used in applications with limited space and lower load requirements. They are commonly used in small electric motors, medical devices, and precision instruments.

  • Max-Type and Conrad Bearings:

Max-type ball bearings have a larger number of balls to increase load-carrying capacity. Conrad bearings have fewer balls and are used in applications with moderate loads and speeds.

  • High-Precision Ball Bearings:

High-precision ball bearings are designed for applications where accuracy and precision are critical, such as machine tool spindles, aerospace components, and optical instruments.

  • High-Speed Ball Bearings:

High-speed ball bearings are engineered to minimize friction and accommodate rapid rotation. They are used in applications such as dental handpieces, turbochargers, and centrifuges.

In summary, the various types of ball bearings are tailored to different application requirements, including load type, direction, speed, and environmental conditions. Selecting the appropriate type of ball bearing ensures optimal performance and longevity in specific applications.
