We Are Proud To Serve The Industry For Over 40 Years!

Greenco/Duramaster is a leading manufacturer of various quality pneumatic linear actuator product lines. We offer a wide variety of pneumatic air cylinder designs including rodless cylinders, guided cylinders, tie rod cylinders and air oil tanks for all kinds of industrial applications. We are known for manufacturing HIGH QUALITY, long lasting designs that stand the test of time!

Greenco offers two space saving cylinder designs, Cable-Trol® and Trac-Trol®. Both cable cylinder designs provide the same stroke as conventional rod cylinders with pneumatic pistons but are approximately 50% SPACE SAVINGS. Our inflatable bladder or short stroke actuator called Powr-Tubes® can provide high forces over both short and long distances.

Duramaster offers a variety of NFPA rod cylinders with pneumatic pistons including NFPA interchangeable tie rod cylinders, NFPA round pneumatic air cylinders and also a complete line of custom air piston double acting pneumatic cylinders. Our air over oil cylinders create smooth, predictable motion by converting pneumatic pressure into hydraulic pressure.
