NCF 2924 CV
Single row full complement cylindrical roller bearing, NCF design
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
