HRQ series pneumatic rotary cylinder

Rack-and-pinion structure ensures smooth operation;
Dual-cylinder design enables double the output force;
High-precision worktable allows for easy load mounting and accurate positioning; a through-hole in the center of the worktable facilitates piping;
(Reserved/Blank)
Positioning holes are provided on both sides (for sizes 10–200) or the bottom (for sizes 2–7) of the cylinder body, ensuring convenient installation;
Two cushioning options are available: fixed cushioning via adjustment screws and hydraulic shock absorbers. The maximum cushioning energy with hydraulic shock absorbers is 3–5 times that of fixed cushioning, offering superior performance. Note: Models HRQ2, HRQ3, and HRQ7 feature only the fixed cushioning method and do not support hydraulic shock absorbers.

HRQ series pneumatic rotary cylinder is a rack-and-pinion rotary actuator (rotary table cylinder) featuring a dual-piston design. It delivers rotary torque to achieve an angular swing of 0–190° and comes with built-in magnets, allowing for the installation of magnetic switches to detect when the rotation reaches the target position.

Operating Principle: Dual pistons drive a rack, which in turn rotates a gear to actuate the upper turntable in a reciprocating oscillating motion. The actual rotation angle can be adjusted via limit screws at both ends. Two cushioning options are available: screw cushioning and hydraulic cushioning (indicated by the model suffix “-A”).

High-precision worktable: Offers high machining precision, easy load mounting, and accurate positioning; features a center through-hole for convenient and flexible piping.

Dual-cylinder structure: Delivers double the output force.

Multiple cushioning options: Choose between adjustable screw-based cushioning and hydraulic damping; the hydraulic damper provides superior cushioning performance.

Rack-and-pinion structure: smooth operation.

Built-in sensor mounting slots: The body features mounting grooves for magnetic switches on both sides.

Available specifications: micro sizes include 2, 3, and 7; medium sizes include 10, 20, 30, and 50; and large sizes include 70, 100, and 200.

Flexible mounting: The cylinder body features locating holes on both sides (sizes 10–200) or the bottom (sizes 2–7), allowing for flexible installation and convenient use.

Note: In actual operation, do not exceed the maximum energy values specified in the table above; doing so may damage internal components and cause product failure.
If the rotation time exceeds the values listed in the table, the hydraulic shock absorber will not be able to provide its full damping performance.
