Angular Contact Ball Bearings

Angular contact ball bearings are designed to handle combined loads—high radial loads plus significant axial (thrust) loads—thanks to their angled raceway geometry. They’re commonly used where stiffness, accuracy, and higher-speed performance matter, such as spindles, pumps, gearboxes, and precision rotating assemblies. For axial loads in both directions, they are often installed as a matched pair (back-to-back or face-to-face).

Key Features

• Handles combined loads: radial + strong axial load (typically one direction per bearing)

• High stiffness & accuracy due to contact angle design

• Good high-speed capability and smooth running

• Available in multiple contact angles (for different axial load capacity)

• Can be used in pairs/sets for bidirectional thrust and improved rigidity

Common Applications

Machine tool spindles, servo motors, pumps, compressors, precision gearboxes, robotics joints, and high-speed rotating shafts.

Selection Notes

Choose based on bore/OD/width, contact angle (higher angle = more axial capacity), and arrangement:

• Single bearing for axial load mainly in one direction

• Paired set (DB/DF/DT) for thrust in both directions and higher rigidity
  Also consider sealing (open/ZZ/2RS), internal clearance/preload, lubrication, and operating speed/temperature.
