Overview
Angular contact ball bearing
Angular contact ball bearings have raceways offset to form a contact angle, accommodating radial loads and axial loads in one direction simultaneously. Mounted in pairs (back-to-back, face-to-face or tandem), they support axial loads in both directions and moment loads. Their high precision and rigidity make them suitable for machine-tool spindles, pumps and gear units.
Key features
- Radial plus single-direction axial load
- Paired arrangements for bidirectional/moment loads
- High precision and rigidity
- Suited to high-speed spindles
Typical applications
- Machine tool spindles and support shafts
- Pumps and compressors
- High-speed motors
- Precision gearboxes and robot drives
Selection guidance
Select by contact angle, arrangement, preload, precision class, axial load direction, and operating speed.
