Other Info.
Motor performance data is based upon an operating temperature of +25°C. Testing in your applications is necessary. You will need to assess duty, cycles and confirm gearbox suitability with your own calculations. Torque figures are to be used for guidance only. Tapped holes on input flange are not relative in position to the gearbox body and will alter from box to box. This also applies to the motor leads. However, we can machine the tapped holes after assembly so they are relative in position to the gearbox body. This will affect delivery.
