By the integral design of the double guide rod and the actuating pressure cylinder, the excellent characteristics of no bias can be improved when the long stroke is actuated. According to the use of precision requirements, in the guide rod bearing part is designed with "sliding bearing", "linear ball bearing". For high speed actuation, it is recommended to use "linear ball bearing" type to improve the actuation accuracy. Considering the ease of installing and pushing out parts for customers, the company for the front end of the piston rod, to the cylindrical connecting block for the launch of the type of standard parts; Only the piston rod end of the cylindrical connecting block, replaced with a platform connecting block, can be used in long actuating stroke lifting type installation; All series are magnetically attached.
