Super precision cylindrical roller bearing for high speed
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
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.
