shell type needle roller bearing

Drawn cup needle roller bearings have a pressed, low-wall outer ring. Drawn cup needle roller bearings are generally used in applications where the housing bore cannot be used as a raceway for a needle roller cage. This requires a very compact and economical mounting. These bearings are mounted with an interference fit in the housing. This allows for a simple and economical design of the housing bore, as shoulders or snap rings are not required to position the bearing axially.
