Direct Coupled Actuators
PRODUCT DATA
FEATURES
Mount directly on 1/2 in. to 3/4 in. (13 to 19 mm) round
or square shaft. Mount on 1 in. (26 mm) round shafts

insert.
300 lb-in. (34 Nm) torque.
Magnetic coupling eliminates need for mechanical
stops or limit switch adjustments by limiting stall
torque, which is dependent on temperature. Nominal
stall torque at room temperature of 68°F (20°C) is 410
