Family specifications and selection conditions
| Product description | 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. |
|---|---|
| Manufacturer features | High radial load carrying capacity • High stiffness • Very low cross-sectional height |
