6.5.1 Life time of ball bearings in MAC141
The curve below can be used to determine the relation between the radial load at the
motor output shaft and where the load is placed at the shaft with reference to the flange
of the motor.
The curves are based on a continuous speed of 3000 RPM.
If the speed is lowered the lifetime will increase inversely proportional.
Example:
A motor is having a radial load of 200N placed with center 10 mm from the flange.
According to the curve the lifetime will be 19000 hours at 3000 RPM.
If the speed is lowered to 300 RPM (10 times lower than the curve is specified at) the
lifetime will increase 10 times giving a total of 190000 hours of operation.
