Where it becomes impractical to meet the shaft raceway design requirements (hardness, case depth, surface finish, etc.) outlined in the engineering section, standard inner rings for drawn cup bearings are available. Inner rings for drawn cup bearings are designed to be a loose transition fit on the shaft and should be clamped against a shoulder. If a tight transition fit must be used to keep the inner ring from rotating relative to the shaft, the inner ring OD as mounted, must not exceed the raceway diameters required by the drawn cup bearing for the particular application.

Drawn cup needle roller bearings support radial loads and reduce friction between rotating components, with a drawn outer shell serving as a raceway to the rollers. The small cross-section of the drawn cup bearing provides high load-carrying capability with minimum required space, drawn cup bearings are easily installed with a press fit in the housing.

Heavy duty Needle Roller Bearings consists of a machined and ground channel-shaped outer ring with a complement of needle rollers and a cage. The high-strength cage retains and guides the rollers. An optional lubrication groove and hole in the outer ring facilitates re-lubrication. These bearings can be used with or without machined and ground inner ring, depending on the suitability of the shaft as a raceway surface.

Thrust Needle Roller and Cage Assemblies are the complements of small diameter needle rollers, arranged in spoke-like configuration. Needle rollers are equally spaced means of cage, its web section separates the rollers and provides guidance to keep them tracking in an orbital path. The purpose of these assemblies is to transmit a thrust load between two relatively rotating objects while greatly reducing friction. Thrust Needle Roller and Cage Assemblies also can be utilized with lipped washer to serve as raceway surface for the needle rollers. Washers can be supplied separately or can be mechanically unitized to the Thrust Needle Roller and Cage Assemblies for ease of handling.
