Rolling and Ball Bearings

Miniature ball bearings for various areas

Daily Use

Rolling bearings/ ball bearings are among the things that move the world. Everybody uses them as a matter of course, but without them our world would stand still. No car, no plane, no drill or washing machine would be able to get by without it.

They are the invisible heroes of our everyday life. A German household has about 160 of them. Wherever parts move or rotate, rolling bearings or ball bearings are used.

Ball Bearings
Wide range of applications

Wide Range of Applications

The miniature ball bearings are available in numerous variations - in stainless steel or chrome steel, flanged, open, shielded - in short, just as your application requires!

Special bearings include, for example, roller bearing systems, dental bearings, X-ray tube bearings or turbocharger bearings (bearing cartridge).

Specially developed for high requirements such as high speeds, low frictional torques, maximum stiffness or low noise level with the smallest dimensions and long product life.
