Manufacturer Ratings
Load-rating symbols are printed as each manufacturer writes them in its own catalogue, so the same quantity can carry a different symbol from brand to brand.
| Brand | Dynamic Load Rating | Static Load Rating | Fatigue Load Limit |
|---|---|---|---|
| SKF 6236 | 229 kN | 240 kN | 6.4 kN |
| NSK 6236 | 250 kN | 241 kN | — |
| Schaeffler (FAG) 6236-M | 240 kN | 244 kN | 10.6 kN |
| NTN 6236 | 252 kN | 241 kN | 11.9 kN |
| Timken 6236 | 227 kN | 241 kN | — |
Speed Ratings
Speed limits depend on sealing and lubrication, and definitions differ by manufacturer. The figures below are for the open version of this bearing. Always confirm the exact variant in the manufacturer's table.
Sealed and shielded versions such as 2Z or 2RS have their own pages; a machined brass cage writing gets its own ↳ row where the catalogue prints a different limit.
| Brand | Grease open / shielded | Oil open | Reference | Limiting |
|---|---|---|---|---|
| SKF 6236 | — | — | 4,000 r/min | 2,600 r/min |
| ↳ 6236 M | — | — | — | 3,800 r/min |
| NSK 6236 | 1,700 r/min | 2,000 r/min | — | — |
| Schaeffler (FAG) 6236-M | — | — | 2,750 r/min | 3,650 r/min |
| NTN 6236 | 1,900 r/min | 2,200 r/min | — | — |
| Timken 6236 | 2,600 r/min | 3,700 r/min | — | — |
↳ rows list a variant's own limiting speed (a shielded version, or a machined brass cage writing) when it differs from the open / standard version; all other figures are shared.
