Product Description:
Angular contact ball bearings play an important role in modern machinery and are widely used in machine tools, automobiles, aerospace and other fields. Angular contact ball bearings can bear radial and axial loads at the same time and adapt to high-speed operation.
Structure and working principle of angular contact ball bearings
Angular contact ball bearings consist of inner ring, outer ring, rolling element (steel ball) and cage. The inner and outer ring raceways are at a certain angle, so that the bearing can bear combined loads. The contact angle is the core design parameter, which determines the axial load capacity of the bearing. The larger the angle, the stronger the load capacity.
Common types of angular contact ball bearings
Single-row angular contact ball bearings: bear unidirectional loads and need to be used in pairs.
Double-row angular contact ball bearings: bear bidirectional loads and have a compact structure.
Four-point contact ball bearings: bear bidirectional loads and are suitable for high axial load occasions.

Carrying capacity: Angular contact ball bearings have high radial and axial load capacity, especially when subjected to large axial loads, its advantages are more obvious. The contact angle of the bearing determines its load capacity and scope of use.
Contact angle: One of the characteristics of angular contact ball bearings is that there is a certain contact angle between its ball and the inner and outer rings, which is usually 15°, 25°, 30°, etc. The larger the contact angle, the stronger the axial load capacity.
Adapt to high loads: Angular contact ball bearings are usually used in applications that need to withstand both radial and axial loads. For example, machine tool spindles, motors, automotive bearings, etc.
Withstand high speeds: Angular contact ball bearings use spherical rolling elements, which have relatively low friction resistance and can operate at higher speeds.
Single row and double row: Single row angular contact ball bearings usually withstand axial loads in a single direction, while double row angular contact ball bearings can withstand axial loads in both directions. Double row types are common in applications that require higher load capacity.
Preload: Angular contact ball bearings are often preloaded to improve stiffness and load capacity. This preload can be achieved through the way the bearing is assembled.
Flexible application: Angular contact ball bearings can be configured with different angles and structures to adapt to different working environments and load requirements.
