The rw series rotary actuator design utilizes two independent piston cylinders, each piston has a crank arm attached to a crankshaft. As the piston strokes in its bore, the crankshaft rotates, pressurizing the opposite bore reverses rotation.
The torque rack on the AR Series produces the rotary output torque while the control rack determines rotary stroke. The output shaft is supported by two angular contact bearings. The NuMate mounting feature provides a convenient method of mounting the AR-Rotaries to the SH-Series linear slide.
