Features

Thin section bearings have a high axial and radial load carrying capacity and at the same time a low coefficient of friction for high speed rotations.
Thin-walled design allows for a wide range of applications in space-constrained environments
Cages made of other materials can be supplied according to the needs of specific applications.
The dimension and running accuracy of the products conforms to tolerance class P4, and products of tolerance class P2 or higher can be supplied on request.
