Rotary pneumatic cylinder

"The rotary pneumatic cylinder can limit the output shaft to a certain angle for reciprocating rotation. According to its structure, it can be divided into two types: blade type and rack type. Blade type: The blade is integrated with the output shaft. Compressed air acts directly on the blade, driving the output shaft to rotate and generate rotational torque. Rack type: The rack is integrated with the piston rod. Compressed air pushes the piston rod to drive the rack to make linear motion, and then the rack pushes the gear to convert it into rotational motion. Finally, the gear shaft outputs torque and drives the external load to swing. "
