| Fatigue load limit | Pu | 7.8 | kN | |
| Attainable speed for grease lubrication | 3900 | r/min | ||
| Attainable speed for oil-air lubrication | 5000 | r/min | ||
| Preload class A | 1100 | N | ||
| Preload class B | 3300 | N | ||
| Static axial stiffnes for preload A | 516 | N/µm | ||
| Static axial stiffnes for preload B | 784 | N/µm | ||
