Key Points of Selection:

It must be chear that the service factor f(See the table below), output speed and motor power when selecting RP series parallel shaft helical geared motor. The service factor fB shows the application and working condition for the working machine. If you want the gears of the speed reducer be durable, the actual service factor of the working machine fBL should lower than fB, that is fBL < fB.
fB: The maxium service factor of the geared motor
fBL: Actual service factor of the working machine
