I. Overview

The electro-hydraulic servo swing actuator (servo swing cylinder, servo torsion actuator) adopts a vane structure inside, which is mainly composed of four parts: a front cover, a rear cover, an integrated housing and a stopper, an integrated piston and a drive shaft . The stopper and the housing are integrally processed, and the stopper is on the inner circle of the housing. They are a part. The piston, namely the blade and the drive shaft, are integrally processed, and the blade and the drive shaft are one part. Compared with rack and pinion and spiral swing cylinder, its piston rotation and drive shaft rotation are synchronized. Therefore, it has no backlash, so it is very suitable for mechanical movement with torsion back and forth and precise positioning.

2. Application characteristics of electro-hydraulic servo pendulum actuator (servo swing cylinder, servo torsion actuator)     

1. Purpose:

    Electro-hydraulic servo swing actuators (servo swing cylinders, servo torsion actuators) are mainly used in motion simulation, fatigue testing, servo turntables, robots, automated production lines and other fields. With years of project implementation experience, Shenling can quickly make suitable and cost-effective servo torsion actuators for users.
