Overview
Combined needle roller / cylindrical roller thrust bearing
These bearings consist of a radial needle roller bearing combined with a cylindrical roller thrust bearing. Together they can accommodate both radial loads and 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.
Key features
- Accommodate radial and axial loads in one direction
- High load carrying capacity
- Low cross section
- Separable design
Typical applications
- Industrial electric motors
- Gearboxes and reducers
- Machine tool spindle support positions
- Rolling mills, paper machines, and heavy machinery
Selection guidance
Choose the N, NU, NJ, or NUP design by load direction, axial locating requirement, cage material, internal clearance, and lubrication condition.
