Cylindrical roller bearing CRB

single-rowsteelceramic

ROBUST Series of Ultra High-Speed Single Row Cylindrical Roller Bearings for machining centres. The optimised materials and designs were developed for high-speed operation with low temperature rise. Condition Description High Speed High Temperature Industries Machine Tools Automation Automotive Production 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
