Material description of spindle bearings

Spindle bearings made of rolling bearing steel
Withstand high load-ratings and are suitable for temperatures up to circa +80°C in the long run, up to circa +120°C in the short run. The steel is wear-resistant, shock-resistant, conductive and magnetic.
Hybrid spindle bearings with ceramic balls and rings made of rolling bearing steel
are subject to a lesser wear and tear compared to bearings of similar size with steel balls. The ceramic balls are current insulating – optimally for the use in engines and generators. Hybrid bearings are lighter than bearings with steel balls of the same size, withstand higher speeds, magnetic and operate in a temperature range from circa -20°C up to +80°C in the long run, up to circa +120°C in the short run.

Spindle bearings / precision angular contact ball bearings — For the highest demands

Spindle bearings are single-row angular contact ball bearings comprising solid inner and outer rings and ball and cage assemblies with solid window cages. They cannot be dismantled. The bearings are available in open and sealed designs.

These bearings are specially designed to offer an exceptionally long lifetime, extreme corrosion resistance and suitability for the highest operating speeds.

Our flexible approach in manufacturing combined with a large stock of different product types enables us to fully meet the demands of our customers at all times.

Features of this design

Spindle bearing
Main dimensions according to DIN 628-1 (at least according to ISO-tolerance class 4). Precision angular ball bearings are usable with high radial loads as well as axial loads in one direction. Axial loads in both directions are also possible in case of installation in pairs in X or O-arrangement. Available with a load angle of 15° (for higher radial loads) or 25° (for higher axial loads). The bearings are not separable.
