Gearmotor — Torque Table
World K Series (General Purpose)
The maximum permissible torque with a decimal gearhead with a gear ratio of 10:1 is 70 lb-in (8 N·m).
The value is 53 lb-in (6 N·m) when 25:136:1 gearheads are connected.

● Gearheads and decimal gearheads are sold separately. Decimal gearheads are not available for V Series.
● Enter the gear ratio in the box () within the model name. A colored background indicates gear shaft rotation in the same direction as the motor shaft; a white background
indicates rotation in the opposite direction.
● The speed is calculated by dividing the motor’s synchronous speed (50 Hz: 1500 r/min, 60 Hz: 1800 r/min) by the gear ratio. The actual speed is 220% less than the
displayed value, depending on the size of the load.
