Mechanical linear actuators are also called motorised mechanical cylinders. These motorized actuators are for industrial applications which require safe operation and linear motion control while moving, turning over or lifting a load. Synchronization, Multiple linkages are synchronized. Simple maintenance, low noise, and normal operation in high or low temperature, anti-corrosion or explosion-proof environment. A compact combination of a common acme screw or ball screw and a reducer and motor. The unique price and performance ratio and unparalleled advantages provide engineers with vast design space. Self-locking, Mostly have an absolute self-locking function, which increases the safety of equipment operation. Precise control with Encoder, transformer, potentiometer are available. Closed-loop precise positioning through inverter, servo controller, and PLC control.
