How manufacturers designate 6312-2Z

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

Manufacturer	Designation	Sealing / design
SKF	6312-ZZC3	2Z – metal shields, both sides
NKE	6312-2Z	2Z – metal shields, both sides
NSK	6312 ZZC3	2Z – metal shields, both sides
NACHI	6312-ZZE	2Z – metal shields, both sides
TIMKEN	6312-ZZ-C3	2Z – metal shields, both sides
KOYO	6312 ZZC4	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 6312-2Z are identical for every manufacturer, so the items in the table are interchangeable – just match the clearance and sealing.
