NK, Machined Type Needle Roller

NK Machined Type Needle Roller Bearing with Inner Race NK Series
The original machined type of needle roller bearing, as invented and introduced by Torrington, employs a caged rollers assembly. The caged bearing combines maximum speed capacity and is supplied with the inner race.
The NK machined outer shell employs the caged needle rollers to provide positive radial retention of rollers even though it may be necessary to remove the shaft repeatedly during the servicing of the mechanism employing the bearing. Needle bearings need to run on harden shafting or harden inner rings.    The NK series is supplied with its matching inner ring. If you don't see your sizes, please Contact Us
