Hydraulic Linear Actuator Details


Oil filler plug: The oil is added or replaced from the plug.

Jacking force adjustment plug: When users unscrew the plug, tighten the nut, the jacking force will increase.

When loosening the nut, the force will decrease.

Retracting force adjustment plug: When users unscrew the plug, tighten the nut, 

the retracting force increases. When loosening the nut, the force decreases.

Safety valve: When the piston rod cannot be withdrawn due to unexpected reasons, 

loosen the safety valve to enable the ejector rod to recover automatically under the action of load force. 

Be sure to screw it tightly before the next time users use it.


Renewable Energy: Solar tracking systems for maximizing energy capture.

Medical Equipment: Hospital bed adjustments for patient comfort.Operating table positioning during surgeries.

Bridge and Dam Construction: Floodgate and barrier positioning.

Oil and Gas Industry: Valve actuators for pipeline flow control.
