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 16052 | 238 kN | 310 kN | 7.2 kN |
| NSK 16052 | 260 kN | 310 kN | — |
| NTN 16052 | 252 kN | 299 kN | 11.1 kN |
Speed Ratings
Speed limits depend on sealing and lubrication, and definitions differ by manufacturer. Contact-sealed variants are normally greased for life and run slower. Always confirm the exact variant in the manufacturer's table.
| Brand | Grease open / shielded | Oil open | Reference | Limiting |
|---|---|---|---|---|
| SKF 16052 | — | — | 3,200 r/min | 2,000 r/min |
| ↳ 16052 MA | — | — | — | 2,800 r/min |
| NSK 16052 | 1,400 r/min | 1,700 r/min | — | — |
| NTN 16052 | 1,500 r/min | 1,800 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.
