How manufacturers designate 6306-RS

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

Manufacturer	Designation	Sealing / design
FAG	6306-C2HRSC3	RS – rubber contact seal, one side
NKE	6306-RSRC3	RS – rubber contact seal, one side
SKF	6306-RS1C3	RS – rubber contact seal, one side
NSK	6306-DUC4	RS – rubber contact seal, one side
KOYO	6306 RS	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 6306-RS are identical for every manufacturer, so the items in the table are interchangeable – just match the clearance and sealing.
