Tolerances and clearances
General bearing specifications

Design considerations
- Shaft and housing tolerances: table
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. Owing to their large number of rollers, the bearings have a high load carrying capacity and stiffness.
- High radial load carrying capacity
- High stiffness
- Very low cross-sectional height
