Customer satisfaction
A hydraulic actuator is a mechanical device that uses hydraulics to convert energy into a linear movement. The mechanical energy produced is generally used to lift or press things that require a great deal of energy. Heavy equipment usually relies on several hydraulic actuators to function.

Common designs for hydraulic actuators consists of the cylinder, piston, hydraulic fluid, and the supply and return line. Majority of the mechanism's process happens inside the cylinder. It contains the piston and hydraulic fluid. An opening inside the cylinder attaches to the supply and return line.
