Deep Groove Ball Bearings FAG 6304 -N

The FAG 6304-N deep-groove ball bearing, with a 20 mm bore and a ring groove in the outer ring, offers a solution for simple axial fixation.

The 6304-N deep groove ball bearing is a single-row rolling bearing from FAG made from standard bearing steel 100Cr6. With main dimensions of 20 mm inner diameter, 52 mm outer diameter and 15 mm width, the component primarily absorbs radial forces as well as moderate axial forces. The open bearing design promotes smooth running, as there are no sealing lips to create additional frictional resistance. A sheet steel cage guides the rolling elements evenly along the raceway.

In which installation spaces is the 6304-N deep-groove ball bearing used?

This rolling bearing is primarily used in designs where axial installation space is limited. The integrated ring groove in the outer ring serves to secure the bearing axially within the housing using a snap ring. This eliminates the need for additional housing shoulders or cover designs. Thanks to its open design, the bearing can be lubricated via a surrounding oil bath or application-specific grease lubrication.

What advantages does the ring groove on the outer ring offer during assembly?

The ring groove on the outer circumference simplifies housing design, as a positive-lock fastening using retaining rings is sufficient. The bearing has standard radial clearance and a tolerance class of P0/PN (corresponding to ABEC 1), making it suitable for standard fits. The component operates within its specified range at operating temperatures from -30 to +120 degrees. As there are no integrated seals, external sealing of the housing to prevent the ingress of contaminants must be provided.
