Values come from the Rotec AI bearing catalogue and are indicative. Confirm against the manufacturer's current catalogue before ordering. Width: 438 mm. Ratings are the published figures for a 241/710 tapered-bore spherical roller bearing of the same size (C 13,900 kN, C0 30,500 kN, grease speed about 170 rpm). The exact maker's table can differ slightly. Confirm before using.
What the designation 241/710 RK means
| Code | Meaning |
|---|---|
| 241 | Spherical roller bearing, double row self-aligning, heavy-duty, extra wide, higher capacity |
| /710 | Bore = 710 mm, stated directly after the slash (bores of 500 mm and above are written this way) |
| K | Tapered bore, taper 1:12, mounted on an adapter or withdrawal sleeve |
| RK | Internal design and cage code of the maker (pressed or machined steel cage, symmetrical rollers, guide ring). The code differs between makers, so check the maker's catalogue. |
Basic rating life of the 241/710 RK
Basic rating life is L10 = (C / P)p million revolutions, where P is the equivalent dynamic load and p = 10/3 (roller bearing). For a 241/710 RK with C = 13900 kN, the table shows what that gives at different load levels. It is the ISO 281 basic life only: it does not include lubrication, contamination, misalignment or reliability modifiers.
| C / P | P as share of C | L10 (million rev) | L10 at 1,500 rpm | L10 at 3,000 rpm |
|---|---|---|---|---|
| 3 | 33.3% | 39 | 430 | 220 |
| 5 | 20.0% | 214 | 2,400 | 1,200 |
| 8 | 12.5% | 1,024 | 11,400 | 5,700 |
| 12 | 8.3% | 3,956 | 44,000 | 22,000 |
For example, a C / P of 5 means the equivalent load is 2780 kN on this bearing. Use the Load Calculator to work out P for your actual radial and axial loads.

Where the 241/710 RK is used
Spherical roller bearings are chosen for: Very high radial load with misalignment capability. Typical equipment: Crushers, mills, conveyors, wind main shafts, paper machines. Robust for shock/dust; lubrication and sealing are crucial.
Common problems on bearings like the 241/710 RK
Most field failures trace back to lubrication, contamination, fits and alignment rather than the bearing itself. These guides explain how to recognise and prevent them:
