- Automotive
- Machine Tools
Product Features
- New SHX heat resistant material 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
Benefits
- High-speed performance: twice that of conventional roller bearings
- SHX material offers a cost effective solution for high speed opreations
- NSK offers SHX rollers as an alternative to ceramic rollers
- Ideally suited for the rear position high-speed main shafts allowing perfect axial thermal displacement of the shaft
- Low heat generation – enabling longer lubricant life
