Question

The dynamic load capacity of a ball bearing is 22 kN. The maximum radial load is kN. If it can sustain to operate at 600 rpm, for 2000 hr, is

• A. 5.29
• B. 6.08
• C. 3.60
• D. 4.16

Answer 1

The correct option is A 5.29

C = 22 kN

$F_{maxradial}=P_e{L}_{90}=\left[\frac{C}{P_e}\right]L_{90}=2000\times 60\times 600L_{90}=72\times {10}^{6}revolution72={\left[\frac{22}{P_e}\right]}^3$

$P_e=5.29\text{kN}$
