2.C clip is adopted to connect the cylinder body and back cover or front cover to make it compact and reliable.

3.The internal diameter of the body is treated with rolling followed by the reatment of hard anodizing, forming an excellent abrasion resistance and durability.

4.The seal of piston adopts heterogeneous two-way seal structure. It has compact dimension and the function of greasel reservation.

5.Compact structure can effectively save installation space.

6.There are magnetic switch slots around the cylinder body, which is convenient to install inducting switch.

7.Double rod non-rotating structure enables to bear large working load and lateral load.
