Combined needle roller / angular contact ball bearing for axial loads in both directions
These bearings consist of a radial needle roller bearing combined with an angular contact ball bearing. Together they can accommodate both heavy radial loads and light axial loads in both directions.
In addition, they can operate at high speeds. Their low cross-sectional height makes the bearings particularly suitable for applications where other types of locating bearing arrangements occupy too much space.
- Accommodate both radial and axial loads
- High load carrying capacity
- High-speed capability
- Low cross section
- Separable design
