Due to the narrow tolerances and special designs available (for example with ceramic rolling elements or bearing rings made from high performance steel), radial super precision bearings can be used in particularly challenging applications.

Spindle bearings

FAG spindle bearings are super precision, single row angular contact ball bearings. Due to their very narrow tolerances, these bearings are particularly suitable for applications involving the highest requirements for guidance accuracy, such as bearing arrangements for main spindles in machine tools.

Cylindrical roller bearings for main spindles

Cylindrical roller bearings for main spindles are available as single or double row designs. They are used where the highest precision is required under very high radial load. Typical areas of application include machine tools and printing machinery. The bearings facilitate bearing arrangements with very high precision, high radial rigidity and very high load carrying capacity. In machine tool building, they provide radial support for the main spindle.
