Values come from the Rotec AI bearing catalogue and are indicative. Confirm against the manufacturer's current catalogue before ordering. Width: 243 mm. Ratings are from a distributor listing of the 24172 ECCJ/W33 (C about 5,737 kN, C0 about 9,300 kN, taper 1:30 on the K30 version). Confirm against the maker's catalogue.
What the designation 24172 ECCK30J/W33 means
| Code | Meaning |
|---|---|
| 241 | Spherical roller bearing, double row self-aligning, heavy-duty, extra wide, higher capacity |
| 72 | bore code "72" = 72 × 5 = 360 mm |
| E | Optimized internal design |
| K30 | Tapered bore, taper 1:30 (for the sleeve or shaft seat on the very large sizes) |
| ECCK30J | 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. |
| W33 | Lubrication groove and three holes in the outer ring, so oil or grease reaches the rollers from the housing. |
Basic rating life of the 24172 ECCK30J/W33
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 24172 ECCK30J/W33 with C = 5737 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 1147.4 kN on this bearing. Use the Load Calculator to work out P for your actual radial and axial loads.

Where the 24172 ECCK30J/W33 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 24172 ECCK30J/W33
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:
