Key Features of 10SR/DA Pneumatic Rotary Actuators

    The 10SR/DA pneumatic actuator uses a dual-rack-and-pinion mechanism with an aluminum alloy body. SR = spring-return (single-acting); DA = double-acting. Bore: Φ45–Φ400 mm. Standard models offer ±4° adjustability at 0° and 90° positions. Max theoretical torque @ 0.8 MPa: DA = 15,800 N·m; SR (K6 spring) = 9,696 N·m @ 0°, 7,488 N·m @ 90°.

Main Features:

    1) Dual-rack design increasingly adopted to boost torque or reduce size (vs. traditional single-rack).

    2) Materials: Body—aluminum with hard-anodized finish (stainless for corrosive media, electropolished). Pinion shaft—stainless steel. Racks—stainless or die-cast aluminum, with composite bearings and wear rings to reduce friction and extend life. Seals—NBR O-rings (standard), FKM for high-temp, low-temp NBR for cold. Integrated anti-leak, bearing-guided shaft design ensures longevity.

    3) Oil-free lubrication—low friction, high reliability.

    4) Magnetic switch compatible for automated control.

    5) Mounting complies with international standards: NAMUR (top ports, shaft keyway), ISO5211/DIN3377 (base)—enabling direct mounting of solenoid valves and limit switches.
