Drawn cup needle roller bearings
SKF drawn cup needle roller bearings have a deep drawn, thin-walled outer ring. 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.
Low cross section
In applications where less space is available, drawn cup needle roller bearings enable downsizing.
High load carrying capacity and stiffness
Owing to their large number of rollers, drawn cup needle roller bearings have a high load carrying capacity and stiffness.
Good running properties
