BSA 202 CGA – Axial angular contact ball bearing (single-sided) for repeatable positioning at high speeds

Quality that safeguards processes
The bearing accommodates axial loads in one direction with high stiffness and runs smoothly with low friction. The precise ball/raceway geometry keeps the frictional torque controlled, thus maintaining the bearing's speed capability . Furthermore, the axial guidance is clearly defined, ensuring stable positioning and repeatability. For axial forces in both directions, it is used as a bearing pair or, alternatively, as a double-sided design.

Design and manufacturing quality
Offset raceways with a large contact angle (e.g., 60°) increase axial stiffness. At the same time, precise cage guidance and finely machined raceways improve rolling performance. Universally paired variants allow for O, X, or tandem arrangements, thus simplifying the design. Since the angular adjustability is limited, precise alignment of the mating surfaces directly affects running accuracy and service life.

Convincing in everyday life
In operation, the high positioning accuracy facilitates the maintenance of constant temperature and vibration levels. Even with high cutting data and frequent start/stop cycles, the quality remains reproducible. If required, double-sided axial guidance can be implemented using a suitable pairing without requiring additional installation space.

Summary
In short: axially strong, speed-resistant and repeatable – for stable processes in precision drives.
