What the designation 7232 BCBM /DB means
| Code | Meaning |
|---|---|
| 72 | Angular contact ball bearing, light dimension series |
| 32 | bore code "32" = 32 × 5 = 160 mm |
| B | 40° contact angle |
| CB | Normal axial internal clearance for a matched pair (universal matching) |
| /DB | Two bearings mounted back-to-back as a matched pair — carries combined radial + axial load from both directions with high stiffness |
Basic rating life of the 7232 BCBM /DB
Basic rating life is L10 = (C / P)p million revolutions, where P is the equivalent dynamic load and p = 3 (ball bearing). For a 7232 BCBM /DB with C = 413.1 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% | 27 | 300 | 150 |
| 5 | 20.0% | 125 | 1,400 | 690 |
| 8 | 12.5% | 512 | 5,700 | 2,800 |
| 12 | 8.3% | 1,728 | 19,200 | 9,600 |
For example, a C / P of 5 means the equivalent load is 82.62 kN on this bearing. Use the Load Calculator to work out P for your actual radial and axial loads.
