Parallel Electric Linear Actuators are used to replace hydraulic or pneumatic cylinders with electrical linear actuators. An electric motor and a lead screw are much easier to run than a pneumatic or hydraulic cylinder. Parallel Heavy Duty Linear Actuators can be self-locking, no chance of a high pressure oil leak and without an additional breaking system, the actuator motion is not controlled. Available lifting force from 100kgf to 25000kgf.
