Learn more about Angular Contact Ball Bearings

In the industrial field, Angular Contact Ball Bearings play a vital role. They are a well-designed bearing type that is widely used in a variety of mechanical equipment and engineering projects.

1. Working principle

Angular Contact Ball Bearings work based on the contact angle between the ball and the track. Angular Contact Ball Bearings have a larger contact angle than other types of bearings, typically between 15° and 40°, which allows them to withstand radial and axial loads from both directions. This design enables the bearing to provide excellent performance under high-speed rotation and high load conditions. Angular Contact Ball Bearings usually consist of inner ring, outer ring, ball, cage and seal. The sphere is located between the inner and outer rings and is kept apart by a cage. When the bearing is subjected to axial load, the balls roll between the inner and outer rings, thereby reducing friction and energy loss.

2. Design features

The design features of Angular Contact Ball Bearings make them one of the first choices for many industrial applications:

Contact angle: Angular Contact Ball Bearings are designed such that the contact angle between the ball and the track is relatively large, thereby increasing the bearing's load-bearing capacity and rigidity. The larger contact angle also helps reduce lateral offset and axial deflection.

Bidirectional Load Capacity: Compared to other types of bearings, Angular Contact Ball Bearings are able to bear both radial and axial loads, which makes them more stable when supporting rotational and tilting movements.

High-speed operation: Due to its design advantages, Angular Contact Ball Bearings are usually suitable for high-speed operation of mechanical equipment, such as wind turbines, automobile transmission systems, etc. Its design reduces rolling friction, thereby reducing heat and energy losses.

3. Industrial applications

Angular Contact Ball Bearings play a key role in various industrial sectors:

Machine tools and machine tools: In machine tools and machine tools, Angular Contact Ball Bearings undertake the important task of supporting the spindle and guide system to ensure that the equipment maintains stability and accuracy when operating at high speed. For example, they are widely used in machine tools such as lathes, milling machines, and drilling machines.

Automotive industry: Angular Contact Ball Bearings are widely used in automobile transmission systems, steering devices, and engines to ensure vehicle performance and safety. On the highway, these bearings need to be able to withstand various loads and vibrations from different directions.

Aerospace: In the aerospace field, Angular Contact Ball Bearings are used to support aircraft engines, landing gear and steering gear systems to ensure the reliability and safety of the aircraft. In extreme environments, these bearings must be able to withstand high temperatures, pressures and high speeds.

7000A-Angular contact ball bearings for precision machinery 
Precision angular contact ball bearing, belongs to the deep groove ball bearing deformation structure, suitable for all kinds of precision machinery selection, this series of bearings can bear radial load and axial load at the same time, can work at a higher speed. The larger the contact angle, the higher the axial load carrying capacity. According to the axial load size, contact angle is mainly divided into C-15 degrees, AC-25 degrees, A-30 degrees, B-40 degrees type structure, small friction coefficient, high limit speed, high manufacturing accuracy, can provide high-speed ceramic ball series bearings and sealed series bearings, cage mainly organic processing window brass cage, steel plate stamping cage, glass fiber reinforced nylon cage (nylon), and phenolic Laminated cloth tube cage (rubber wood), also can provide universal pair and any pair combination bearings.
