Category FAQ

Common questions before sending an inquiry.

01Pneumatic Rotary ActuatorsHow do I select torque for a pneumatic rotary actuator?

Start with the load, lever arm, inertia, motion angle, acceleration, and available air pressure, then include a suitable safety margin.

02Pneumatic Rotary ActuatorsWhat is the difference between rack-and-pinion and vane rotary actuators?

Rack-and-pinion actuators are often chosen for stronger torque and robust output. Vane actuators are compact and smooth for lighter angular motion.

03Pneumatic Rotary ActuatorsWhat details help with a rotary actuator replacement?

Send model code, photos, output shaft dimensions, angle, torque or load, mounting holes, port size, and sensor or stop adjustment details.
