JOJI drawn cup needle roller bearings feature a deep-drawn, thin-walled outer ring. Drawn cup needle roller bearings are typically used in applications where the housing bore cannot serve as a raceway for the needle roller and cage assembly, yet a very compact and economical bearing arrangement is required. These bearings are mounted in the housing with an interference fit. This allows for a simple and economical design of the housing bore, as no shoulder or retaining ring is required to axially locate the bearing.
The hardened steel drawn outer ring forms a non-separable unit with the needle roller and cage assembly of these bearings.
