How manufacturers designate 6405

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

Manufacturer	Designation	Sealing / design
NKE	6405	Open
KOYO	6405 C3	Open
NTN	6405	Open
NSK	6405	Open
FAG	6405	Open
SKF	6405 C3	Open

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 6405 are identical for every manufacturer, so the items in the table are interchangeable – just match the clearance and sealing.
