NX 30
Combined needle roller / thrust ball bearing (full complement thrust part) with a cover with lubrication holes
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 has a cover with lubrication holes.
- Accommodate radial and axial loads in one direction
- High load carrying capacity
- Low cross section
- Non-separable design
