Tolerances and clearances
General bearing specifications
- Tolerances: Normal
- Radial internal clearance: table
Bearing interfaces
- Seat tolerances for standard conditions
- Tolerances and resultant fit
Single row full complement cylindrical roller bearings are designed to accommodate very high radial loads in combination with moderate speeds. The bearings incorporate a maximum number of rollers as they are not equipped with a cage. Having two integral flanges on the inner ring and one flange on the outer ring, NCF design bearings can accommodate axial displacement in one direction. A retaining ring on the outer ring holds the bearing together. The retaining ring should not be loaded axially during operation.
- Very high radial load carrying capacity
- High radial stiffness
- Long service life
- Locate the shaft axially in one direction
