Tolerances and clearances
General bearing specifications
- Tolerances: table 1, table 2
- Radial internal clearance: Standard inner ring, Other bearings
Bearing interfaces
- Shaft tolerances
Insert bearings are based on sealed deep groove ball bearings. This variant is suitable for applications with both constant and alternating directions of rotation, heavy loads and/or high speeds. It has an inner ring extended on both sides and uses NR ConCentra locking technology, enabling quick and easy mounting onto the shaft.
- Quick and easy to mount onto the shaft
- Long service life
- Reduce noise and vibration levels
