Product structure
A. Prestressing Mono jack tensioning cylinder and return cylinder both adopt double seal to improve seal reliability. Prestressing the key connection between the small cylinder and the second cylinder, the small cylinder and the rear end cover, and the small cylinder and the tool ring of Mono jack are used to prevent rotation. Prestressing Mono jacks are sealed with Grey-ring or Sterring for reliable sealing.
B, Prestressing Mono jack two cylinder and piston head design as a whole form, to avoid the possibility of failure due to two-body welding or two-body connection by thread. It increases the difficulty of machining process, but improves the reliability.
C. Prestressing Mono jack wear-resistant ring and wear-resistant sleeve improved design to avoid the possibility of the assembly type being forced out and improve product reliability.
D. Prestressing Mono jack All important parts are made of high quality alloy structure or tool steel to improve hardness and strength
