Numatics™ Series RW 90° Rotary Actuators
ASCO Numatics Series RW 90° Rotary Actuators
The Numatics Series RW 90-degree rotary actuators are designed with two independent piston cylinders that have crank arms attached to crankshafts.
As the piston strokes in its bore, the crankshaft rotates. Pressurizing the opposite bore reverses rotation. The rotary actuators are suitable for winemaking, analytical and diagnostic equipment, automotive, biofuels, and bottling applications.
