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.
