GMK is well known for AT actuators. The actuator has the honed cylinder surface of the extruded aluminum. ASTM6005 body provides longer life and a lower coefficient of friction. You can achieve the reverse rotation in the field by simply flipping the pistons, thanks to the rack and pinion design's dual pistons, which also allow for compact construction, a symmetric mounting location, a high-cycle life, and rapid operation. Our goods meet or exceed the requirements of NAMUR and ISO5211, and they are made in facilities that are ISO 9001:2000 and CE certified.
