Family specifications and selection conditions
| Product description | These bearings consist of a radial needle roller bearing combined with a full complement thrust ball bearing. Together they can accommodate both moderate radial loads and lighter axial loads in one direction. Their low cross-sectional height makes the bearings particularly suitable for applications where other types of locating bearing arrangements occupy too much space. The thrust part is capped with a cover that forms a gap-type seal to retain the grease in the bearings. |
|---|---|
| Manufacturer features | Accommodate radial and axial loads in one direction • High load carrying capacity • Low cross section • Non-separable design |
