Tolerances and clearances
General bearing specifications
- Tolerances: Normal, P6, P5,
tapered bore 1:12, tapered bore 1:30 - Radial internal clearance: cylindrical bore, tapered bore
Bearing interfaces
- Seat tolerances for standard conditions
- Tolerances and resultant fit
Spherical roller bearings can accommodate heavy loads in both directions. They are self-aligning and accommodate misalignment and shaft deflections, with virtually no increase in friction or temperature. They can be used in a modular system, including housings, sleeves and nuts.
- Accommodate misalignment
- High load carrying capacity
- Low friction and long service life
- Increased wear resistance
