FAQ

To guarantee continuously smooth operation, shaft deflection should be minimal. A maximum deflection of 0,01 mm between the first and last outer balls in the ball bearing is acceptable.
f 1 = deflection under central load in mm.
P = load in kp. 
L = distance between the supports in mm.
D = diameter of the shaft in mm.
f 2 = deflection for a load shared on two symmetrical points with respect to the center, in mm.
a = according to drawing.
b = according to drawing.

f 3 = deflection under a load acting on the free end, in mm.
