How manufacturers designate 6308-2RZ

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

ManufacturerDesignationSealing / design
NSK6308-VV2RZ – rubber non-contact seals, both sides
NTN6308 LLBCM/5K2RZ – rubber non-contact seals, both sides
SKF6308-2RZTN9/HC5C3WT2RZ – rubber non-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 6308-2RZ are identical for every manufacturer, so the items in the table are interchangeable – just match the clearance and sealing.
