Rotor Shaft Assembly Turn-Act's patented rotor/vane assembly eliminates the possibility of shaft rotation in the rotor and permits the use of a wide variety of shaft materials. Output shafts can be custom ordered for specific application requirements. The Gold Seal Turn-Act's patented polyurethane seal provides smooth rotation, minimal leak rate, low pressure breakaways and millions of cycles. Bolt Lobe Air Inlets The large hole permits more rapid air entry and exhaust for faster response time. Shaft Bearings Full Complement needle bearings accommodate substantial radial loads. Machined Aluminum Heads Stator Unitized Body Turn-Act's patented extrusion combines tube, stator and bolt lobes into a one-piece unitized body. Unique design provides torsional rigidity allowing the unit to stop and hold shaft loads internally, while effectively transmitting shocks to its mountings. SINGLE VANE ACTUATOR Single vane actuators have a cylindrical chamber in which a vane/rotor shaft assembly rotates through an arc of approximately 274. Two air chambers are separated by a non moving stator. Air pressure applied to the vane/rotor rotates the shaft until the vane/rotor meets the stator. Rotation is reversed by reversing the air pressure at the inlet and outlet ports. DOUBLE VANE ACTUATOR Double vane actuators have two diametrically opposed vane/rotors and stators. Air pressurizes opposed chambers through cross drilled holes (dotted lines) in the vane/rotor and shaft. Double vane actuators provide twice the torque of same size single vane actuators. Rotation is limited to 94. FEATURES: Twelve models with torques from 9 - 60 in. lbs.
