General Studies · Bearings
If P = equivalent dynamic load (N), Fr = radial load (N), Fa = axial or thrust load (N), V = race-rotation factor, and X and Y are radial and thrust factors respectively, then the expression for the equivalent dynamic load is given by:
- 1P = XFa - YVFr
- 2P = XVFr + YFa✓
- 3P = XFa + YVFr
- 4P = XVFr - YFa
Correct answer
P = XVFr + YFa
