KNL122036 KNL series Needle bearing and Cage Assemblies

Description

Introduction of  Drawn cup needle bearings

Drawn cup needle bearings are designed to support radial loads and reduce friction between rotating components. The low cross section provides maximum load-carrying capability with a minimum of space required. Drawn cup bearings are easily installed with a press fit in the housing.

There are two basic designs: the full complement and the caged version. Both have a drawn outer shell that serves as a raceway for the rollers contained in the bearing. The full complement version has the maximum number of rollers mechanically retained by the drawn outer shell. This design combines high radial load-carrying capability with low cost. The standard caged version contains a one-piece steel cage to guide and retain the rollers. This design provides high speed and maximum lubricant retention capability.

drawn cup needle roller bearings design features

 Torque can be transmitted by either the housing or the shaft.
 Torque is positively transmitted by rollers that wedge against interior ramps.
 Transition from free motion to lock occurs with minimal backlash or lost motion.
 Available as clutch-only or as a clutch and bearing assembly.
 Clutch-only units should be used with external radial support to hold the shaft and housing.
