Drawn Cup Needle Roller Bearing type includes an outer ring and needle rollers, which are both drawn from special thin steel plate by precision deep drawing, and a cage which guides the needle rollers precisely. A hardened and ground shaft or inner ring (IR Series) is used as the raceway. This bearing needs no axial clamping due to easy installation and a press-fit in the housing. Both closed end type to close around the end of the shaft and an open end type are available. Furthermore, a type with a seal installed on a single side or on both sides is also available.
