Values come from the Rotec AI bearing catalogue and are indicative. Confirm against the manufacturer's current catalogue before ordering. Width: 60 mm. Rating C 614 kN is from a current distributor listing. An older SKF table value is 585 kN. Confirm against the maker's catalogue.
What the designation 23032 CCK/C3W33 means
| Code | Meaning |
|---|---|
| 230 | Spherical roller bearing, double row self-aligning, heavy-duty wide series |
| 32 | bore code "32" = 32 × 5 = 160 mm |
| K | Tapered bore, taper 1:12, mounted on an adapter or withdrawal sleeve |
| CCK | 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. |
| C3 | Radial internal clearance larger than normal. Used where the inner ring runs warmer than the outer or with an interference fit. |
| 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 23032 CCK/C3W33
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 23032 CCK/C3W33 with C = 614 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 122.8 kN on this bearing. Use the Load Calculator to work out P for your actual radial and axial loads.

Where the 23032 CCK/C3W33 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 23032 CCK/C3W33
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:
