Compact design
Depending on the design, the bearing may have its own inner ring or run directly on a prepared shaft surface. The assembly design therefore directly affects the hardness, geometry, and surface-condition requirements of the running surface.
What matters for a needle-roller support
- Available radial space.
- Radial load.
- Presence or absence of an inner ring.
- Condition of the shaft running surface.
- Accuracy of the fit geometry.
- Lubrication.
- Speed and type of motion.
- Permissible misalignment of the assembly.
