Gear rack swing oil cylinder

product overview

The gear rack swing cylinder is a Hydraulic Actuator that converts hydraulic energy into limited angle rotary motion. It drives the rack motion on the piston through hydraulic oil, and drives the gear shaft that meshes with it to achieve rotational output.

Working principle

1. Pressure oil enters the cylinder and drives the piston to move in a straight line

2. The rack on the piston drives the gear to rotate

3. Gear shaft output rotational torque

4. Change the direction of the oil circuit through a Directional Valve to achieve forward and reverse rotation

main features 

-* * High torque output * *: The gear rack transmission structure can provide high torque

-* * Precise angle control * *: can achieve precise angular positioning (usually 90 ° -270 °)

-* * Compact structure * *: Compared to blade type swing cylinders, it has a smaller volume

-* * Long service life * *: Wear resistant design, easy maintenance

-Flexible Installation: Multiple Installation Methods to Choose from
