How manufacturers designate 61811-2RS

| Manufacturer | Designation | Sealing / design |
|---|---|---|
| NKE | 61811-2RSR | 2RS – rubber 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 61811-2RS are identical for every manufacturer, so the items in the table are interchangeable – just match the clearance and sealing.
