How manufacturers designate 6308-2RS

Manufacturer	Designation	Sealing / design

ZEN	6308-2RSC3	2RS – rubber contact seals, both sides
NKE	6308-2RS2C3	2RS – rubber contact seals, both sides
FAG	6308-2RSRC3	2RS – rubber contact seals, both sides

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 6308-2RS are identical for every manufacturer, so the items in the table are interchangeable – just match the clearance and sealing.
