China factory 3124m Double Row Angular Contact Ball Bearing for Transmission wheel bearing

Product Description

Product Description

 

Angular contact ball bearing can support radial load and axial load. As single row angular contact ball bearings can only support axial load in single direction, it often adopts mounting in pair. As matched pairs of bearings, preload for them is more convenient. Retainer are made of brass, synthetic resins or others subject to individual bearing feature and application conditions.
 

 

The raceways of angular contact ball bearing in the inner and outer rings can have relative displacement on the horizontal axis. Therefore, this design can make it withstand combined loads, namely, supporting radial and axial loads simultaneously. The axial load capacity of angular contact ball bearing improves with the increasing contact angle.

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.

How do Ceramic Ball Bearings Compare to Traditional Steel Ball Bearings in Terms of Performance?

Ceramic ball bearings and traditional steel ball bearings have distinct characteristics that can impact their performance in various applications. Here’s a comparison of how these two types of bearings differ in terms of performance:

  • Material Composition:

Ceramic Ball Bearings:

Ceramic ball bearings use ceramic rolling elements, typically made from materials like silicon nitride (Si3N4) or zirconium dioxide (ZrO2). These ceramics are known for their high hardness, low density, and resistance to corrosion and wear.

Traditional Steel Ball Bearings:

Traditional steel ball bearings use steel rolling elements. The type of steel used can vary, but common materials include chrome steel (52100) and stainless steel (440C). Steel bearings are known for their durability and strength.

  • Friction and Heat:

Ceramic Ball Bearings:

Ceramic bearings have lower friction coefficients compared to steel bearings. This results in reduced heat generation during operation, contributing to higher efficiency and potential energy savings.

Traditional Steel Ball Bearings:

Steel bearings can generate more heat due to higher friction coefficients. This can lead to increased energy consumption in applications where efficiency is crucial.

  • Weight:

Ceramic Ball Bearings:

Ceramic bearings are lighter than steel bearings due to the lower density of ceramics. This weight reduction can be advantageous in applications where minimizing weight is important.

Traditional Steel Ball Bearings:

Steel bearings are heavier than ceramic bearings due to the higher density of steel. This weight may not be as critical in all applications but could impact overall equipment weight and portability.

  • Corrosion Resistance:
