Tolerances and clearances
General bearing specifications
- Tolerances:
bearings: Normal and CL7C, P5
inch bearings: Normal and CL - Internal clearance
Bearing interfaces
- Seat tolerances for standard conditions
- Tolerances and resultant fit
NR double row tapered roller bearings are available in many designs and variants, such as double row tapered roller bearings in TDI and TDO designs, and matched single row tapered roller bearings. Depending on their design, the bearings can accommodate heavy radial loads, axial loads in both directions and have a high degree of stiffness.
- High radial load carrying capacity
- Accommodate axial loads in both directions (except for tandem arrangements)
- High stiffness
- Low friction
- Long service life
