How manufacturers designate 6304-RS

Each brand uses its own seal and design codes. The designations below describe the same bearing.

Manufacturer	Designation	Sealing / design
FAG	6304-C2HRSC3	RS – rubber contact seal, one side
NKE	6304-RSR	RS – rubber contact seal, one side
SKF	6304-RSHC3	RS – rubber contact seal, one side
NSK	6304 DU	RS – rubber contact seal, one side

2RS, 2Z or C3 – which to choose?

2RS (two rubber seals) keeps dust and moisture out but limits speed. 2Z (metal shields) does not touch the ring, so it runs faster and cooler but protects less. 2RZ is the compromise – a non-contact seal.

Choose C3 clearance when the bearing runs hot (electric motors, fans) or with a tight shaft fit. Normal clearance CN is enough for ordinary applications.

The dimensions of 6304-RS are identical for every manufacturer, so the items in the table are interchangeable – just match the clearance and sealing.
