What the designation 30216 means
| Code | Meaning |
|---|---|
| 302 | Tapered roller bearing, standard contact angle series |
| 16 | bore code "16" = 16 × 5 = 80 mm |
Basic rating life of the 30216
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 30216 with C = 184 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 36.8 kN on this bearing. Use the Load Calculator to work out P for your actual radial and axial loads.
