What the designation 22320 E means
| Code | Meaning |
|---|---|
| 223 | Spherical roller bearing, double row self-aligning, medium series (higher capacity) |
| 20 | bore code "20" = 20 × 5 = 100 mm |
| E | Optimized internal design |
Basic rating life of the 22320 E
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 22320 E with C = 847 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 169.4 kN on this bearing. Use the Load Calculator to work out P for your actual radial and axial loads.
