A self-aligning ball bearing has a basic dynamic load rating (C10, for 106 revolutions) of 35 kN. If the equivalent radial load on the bearing is 45 kN, the expected life (in 106 revolutions) is
-
- below 0.5
- 0.5 to 0.8
- 0.8 to 1.0
- above 1.0
Correct Option: A
| Life (in Million Revolution) = |  | C |  | q | ||
| Pe |
q → 3 = ball bearing
| q → | ⇒ Roller bearing | 3 |
| Life = | | 35 | | 3 = 0.4705 Million Revolution | ||
| 45 |
C → Dynamic load capacity = 35 KN
Pe equivalent load = 45 KN
