Product Description

Angular Contact Ball Bearings: Functions & Applications

Angular contact ball bearings are engineered to withstand both radial and single - direction axial loads simultaneously. Their contact angle (ranging typically from 15° to 40°) directly enhances axial load - bearing capacity, with larger angles delivering stronger axial load resistance. These bearings excel in high - speed operations while maintaining rotational precision.
 
Key Applications: Widely used in machine tool spindles, electric motors, pumps, compressors, automotive transmissions, and aerospace components where high precision and combined load resistance are required.
