Thrust needle roller and cage assemblies are complements of small diameter needle rollers, arranged in a spoke-like configuration. Needle rollers are equally spaced by means of a 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 unitized with lipped washers to serve as raceway surfaces 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.

Ideally, a thrust washer should be stationary with respect to and piloted by its supporting or backing member whether or not this is an integral part of the shaft or housing. There should be no rubbing action between the thrust washer and any other machine member. The economics of design, however, often preclude these ideal conditions and thrust washers must be employed in another manner. In such cases, design details should be determined in consultation with your representative.

Koyo JTT-1012 Inch Series Caged Open Ends Drawn Cup Needle Roller Bearing, 5/8 in Dia Bore, 13/16 in OD, 3/4 in W, 1980 lbf Dynamic/2910 lbf Static Load

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.

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 Clutches are similar to drawn cup needle roller bearings in design, however, they allow free rotation in only one direction while transmitting torque in the opposite direction. These designs use the same small radial section as drawn cup needle roller bearings and are offered as clutch-only units or as clutch and bearing assemblies.
