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
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
