Hollow Hydraulic Cylinder Rod:
Suitable for Elevator Cylinder, Telescope Cylinder, Scaling Ladder, Agriculture Machines, Earthwork Machines, etc.

Product Features:
● A higher Yield Strength, with good weld-ability.
● Easy for mechanical property and the Low Temperature Enduring Assault Performance better that generally tubes.
● The internal precise ground and the external hard chrome plated after precise grinding, that tolerance meet with international standards.

The hollow piston rod is the connecting part that supports the piston rod to do work, most of them are used in hydraulic cylinder and pneumatic cylinder motion execution parts. Therefore, the hollow piston rod is required to have sufficient strength, stiffness and stability. Take Hydraulic cylinder for example, It is mainly composed of cylinder, piston rod (cylinder rod), piston and end cover. The quality of its processing directly affects the life and reliability of the whole product. Hollow piston rod needs higher machining precision & strict surface roughness, and also demands strict requirements on straightness and wear resistance. The basic feature of hollow cylinder piston rod is the processing of slender shaft, which is difficult to process. Our company has an excellent R & D team, experienced workshop workers, strictly control the quality of each link of production. If you have any requirement, please contact us freely.
