3.The sturcture advantage ??? ??? 1)On the right structure, we combine the cylinder and slider, overall casting into integrated side rollers’ sliding cylinders, substantial increase the contact area between the slider and guide rails, so then increase the stability of side rollers’ slide work. ??? 2)On the right structure, we combine the cylinder and slider, reduce the guide rail length, lower the centre-of-gravity of the overall device, and increase the stability of the device. ??? 3)On the right structure, we adopts inverted cylinder, in order to protect the seals, so then increase cylinders’ life, and reduce the failure rate of the device. ??? 4)From the drawing and the real device photos, we will find the line guide structure is more complex, of course it means higher production costs for manufacturer. 4.
