Needle Roller Bearings
Advantages:
- Low cross section
- High load carrying capacity
- High stiffness
- The possibility of assembling inner and outer rings separately permits interference fits for shaft and housing and also enables easy maintenance inspections
- Accommodate axial displacement Except for bearings with flanges on both the inner and outer rings, needle roller bearings with machined rings can accommodate axial displacement
- Accommodate static misalignment
- Locating bearing arrangement Combined needle roller bearings accommodate combined radial and axial loads in one or both directions
