Servo electric cylinders are mainly used in experimental equipment, special equipment, military equipment and other fields, as well as other places that can replace hydraulics and pneumatics. They are upgraded products of hydraulic and pneumatic equipment, such as all-electric multi-degree-of-freedom platforms.

[0003] In the process of using the servo electric cylinder, it is often necessary to adjust the transmission direction of the servo electric cylinder according to different needs. At the same time, when installing and fixing the servo electric cylinder, it is often necessary to use a large number of bolts to assist in fixing it.
