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 in the YET 2 series, supplied with already fitted rubber seating rings. Located between the bearing outer ring and housing bore, the rubber seating ring dampens vibration and noise and enables the bearings to be displaced slightly in their housings and to accommodate minor shaft expansion or misalignment.
- Quick and easy to mount onto the shaft
- Accommodate static initial misalignment
- Long service life
- Reduced noise and vibration levels
