How manufacturers designate 6812-2Z

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

Manufacturer	Designation	Sealing / design
NACHI	6812 ZZE	2Z – metal shields, both sides
NTN	6812-ZZ5K	2Z – metal shields, both sides
KOYO	6812 ZZ	2Z – metal shields, both sides
NSK	6812-ZZ	2Z – metal shields, 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 6812-2Z are identical for every manufacturer, so the items in the table are interchangeable – just match the clearance and sealing.
