REQUEST MORE INFO

This listing is for two servo hydraulic linear actuators mounted vertically for use in automotive structural testing. These two actuators were from a set of four used in a 4-post test rig for structural testing of vehicles. Actuators are rated at 5.5 kips with a 12" stroke, but their construction is much more heavy-duty than similarly rated actuators. They feature 2" thick mounting plates, strengthening gussets, 5" piston diameters, hydrostatic bearings, and large servo valves. The servo valve is mounted to the side of the actuator and is controlled with a pilot operated control valve. There is also an LVDT installed with connection diagram printed directly on the unit. The actuators could be duplicated to make a  4-poster test system, be used as a 2-poster for motorcycles or recreational vehicles or they could be re-purposed wherever an actuator of this size and shape would be needed. The units are in good overall condition with the only noticeable defect being one of the servo valve electrical connection covers is cracked.
