NCF 29/600 V

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
