Drawn cup needle bearings are designed to support radial loads and reduce friction between rotating components. There are two basic designs: the full complement and the caged version.
Drawn cup roller clutches are designed to transmit torque between the shaft and housing in one direction and allow free overrun in the opposite direction.
Needle roller and cage assemblies consist of a complement of needle rollers held in place by a cage. With no inner or outer ring, the low cross section provides maximum load-carrying capability within the smallest envelope.
Heavy-duty needle roller bearings provide maximum load capacity and shock resistance with a relatively small radial cross section.
