Drawn cup needle roller bearings are typically used in applications where the housing bore cannot be used as a raceway for a needle roller and cage assembly, but where a very compact and economical bearing arrangement is required. These bearings are mounted with a tight interference fit in the housing. That enables a simple and economic design of the housing bore, as shoulders or snap rings are not required to locate the bearing axially. The drawn cup of hardened steel and the needle roller and cage assembly of these bear­ings form a non­-separable unit.Accommodate heavy axial loads and peak loads The very small diameter deviation of the rollers within one assembly enables these bearings to accommodate heavy axial loads and peak loads. Extended bearing service life To prevent stress peaks, the roller ends are relieved slightly to modify the line contact between the raceway and rollers.
