Additional Details
NNCF type bearings have three flanges attached as a single piece to the inner ring and one flange attached as a single piece to the outer ring. This allows the bearing to be axially oriented in one direction. A retaining ring is inserted in the outer ring on the opposite side of the flange and serves to hold all the components together.
