ROBUST™ Series Ultrahigh-Speed Single Row CRB
ROBUST™ Series of Ultra High-Speed Single Row Cylindrical Roller Bearings for machining centres. Optimised materials and designs developed for high-speed operation with low temperature rise.
Product Features
- New SHX heat resistant material option for high speed.
- Three design options: RS (Standard bearing steel rings & rollers), RX (Special SHX bearing rings & SHX rollers) & RXH (Special SHX bearing rings & ceramic rollers)
- Special design outer ring guided PEEK cage
Product Benefits
- High-speed performance: twice that of conventional roller bearings.
- SHX material enables a cost effective solution for high speed.
- NSK offers SHX rollers as an alternative to ceramic rollers.
- Ideally suited for the rear position of high-speed main shafts allowing perfect axial thermal displacement of the shaft.
- Low heat generation – enabling longer lubricant life.
- Outer ring temperature rise is 30% lower than conventional.
- Longer fatigue life due to special SHX material (up to 4x ).
- PEEK resin cage gives stable bearing rolling movement under high speed operating conditions.
