Super-precision single row cylindrical roller bearing
These super-precision single row cylindrical roller bearings have a tapered bore and can accommodate axial displacement of the shaft relative to the housing in both directions.
They are available in basic design and high-speed design.
- Accommodate high speeds
- Low friction
- Separable
