Tolerances and clearances
General bearing specifications
- Tolerances: Normal, 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
CARB toroidal roller bearings are unique: as well as accommodating misalignment without increased stress levels, they also provide frictionless axial movement within the bearing in the non-locating position in self-aligning bearing arrangements. This full complement bearing, which has a lower speed rating, uses as many rollers as possible, giving it the highest possible load rating.
- Accommodate misalignment and axial displacement within the bearing
- Very high radial load carrying capacity
- Provide frictionless axial movement
- Long bearing system life
