High-speed spindle bearings are specially designed for maximum speeds and precision. Optimised internal geometries, defined contact angles and smooth-running cage systems enable particularly smooth running even at extreme speeds. Small ball diameters reduce centrifugal forces and ensure uniform temperature behaviour during operation.
The bearings are available in various preload classes and are often used in sets to maximise the rigidity and accuracy of tool or motor spindles. Thanks to their manufacture within tight tolerances, they ensure consistent concentricity, high speed limits and reproducible machining results.
Depending on the application, variants with hybrid balls, special sealing systems or adapted lubricant solutions are available. This allows high-speed spindle bearings to be precisely adapted to the requirements of modern high-performance machines – for dynamic processes, maximum running smoothness and long service life.
