What is the mechanism of a hydraulic rotary actuator?

This hydraulic device operates on a design involving multiple helical gears. The rotation of these gears are driven by the piston, translating linear motion into rotational movement. The design of the hydraulic rotary actuator is simple but requires precision manufacturing to ensure functional efficiency and brand reliability.

What are the advantages of helical hydraulic rotary actuators?

The rotary actuator is a compact hydraulic device suitable for applications requiring heavy load tilting or rotational movements (involving high torque). It is easy to control, highly precise, and efficient. Despite its high power, it requires minimal installation space. The rotary actuator achieves high functional efficiency and reliability. Internally, it is protected from dust, dirt, and moisture.

Where can your LS5 series hydraulic rotary actuator be applied in construction machinery?

Our LS5 series hydraulic rotary actuator is specifically designed for excavators, primarily used for the rotation of excavator buckets.
