Angular Contact Ball Bearings

Angular contact ball bearings support both radial and axial loads through asymmetric races that house the bearing’s spherical rolling elements, also called bearing balls, on an angle. The deeper the angle between the bearing and its axis, the greater the axial load the bearing can carry.Angular Contact Ball. Timken ® angular contact ball bearings are designed for combination radial and axial loading. Single-row bearings have high thrust capacity in one direction. Some single-row bearings are specifically designed for duplex mounting in sets for maximum performance.


Angular contact bearings have a much higher speed rating than radial ball bearings because of the nonstop contact of the balls to both raceways. Angular contact bearings can carry both radial and axial loads that are transferred from one ring to the other, through the balls, along a specific contact angle. Angular contact ball bearings are often preloaded to enhance their rigidity and rotating performance. For high-precision matched pair angular contact ball bearings of class 5 or higher, which are used in machine tools and other precision equipment.
