Needle roller bearing components SKF supplies both inner rings for needle roller bearings and needle rollers as separate needle roller bearing components. Inner rings are typically combined with needle roller and cage assemblies or drawn cup needle roller bearings in applications where the shaft cannot be hardened and ground.

Needle rollers. are made of carbon chromium steel; have a hardness of 58 to 65 HRC; have a precision ground surface For assistance in designing full complement bearing arrangements or to calculate performance data for these bearing arrangements, contact the SKF application engineering service.
