How manufacturers designate 6820-2Z
Each brand uses its own seal and design codes. The designations below describe the same bearing.
| Manufacturer | Designation | Sealing / design |
|---|---|---|
| NSK | 6820-ZZ | 2Z – metal shields, both sides |
| NACHI | 6820 ZZ | 2Z – metal shields, both sides |
| NTN | 6820 ZZ/5K | 2Z – metal shields, both sides |
| KOYO | 6820 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 6820-2Z are identical for every manufacturer, so the items in the table are interchangeable – just match the clearance and sealing.
