Drawn cup needle roller bearings, as the name suggests, are needle roller bearings with a deep drawn thin-walled outer ring with open or closed end. They are characterised by very low sectional height and high load carrying capacity. They are used when the housing bore cannot be used as a raceway for a needle roller and cage assembly but where a very compact and economic bearing arrangement is required. They are pressed into the housing bore and, if shoulders or retaioning rings are not required for axial location, the design of the housing bore is simple and can be economically produced.
