Hybrid bearings provide highest speeds with long life

Hybrid bearings provide highest speeds with long life
NSK has combined its exclusive SHX bearing steel, and ceramic rolling elements to produce ultra high-speed hybrid angular contact bearings that can operate reliably at speeds up to 3.3 x 106 dmn (around 47,100rpm for a 70mm bore bearing). The synergy achieved between the materials in the bearings also enables the Robust hybrid series to offer the user the benefits of lower heat generation, high seizure resistance, better temperature stability, and greater stability during high-speed operation. The superior performance characteristics of the new Robust series of hybrid bearings mean that they are ideally suited to high-speed machining operations where conventional angular contact bearings would be beyond their operating limits. 

The new bearings satisfy the exacting demands of the latest generations of motorised machine tool spindles for smooth running - even during periods of rapid acceleration, where their higher levels of temperature tolerance, low heat generation and resistance to seizure help to improve bearing life.

The Robust hybrid series of angular contact ball bearings is available in three types: H, X and XE. The base unit in the series is the hybrid H type, with silicon nitride balls and bearings rings manufactured from NSK's long life Z steel.
