Product Feature

1.Light-weight,high strength

   Base on the nature of construction work,the hydraulic cylinders need to suit for high strength,high

   using frequency,high fatigability.to promise the sability and reliablity of application.

2.the seal system

   select the excellent seal kits from japan and germany.adopt the advanced physical design,make

   sure the hydraulic cylinder get the best piston rod oil film

3.cylinder body

   adopt the good-quality alloy honed tube,though cold-drawing and rolling,to reach an excellent

   toughness and surface hardness.improve the wear-resistance.

4.piston rod

   middle frequency induction hardening and tempering,chrome plated on rod surface to improve the

   anti-rust ,wear-resistance and anti-scratch property.

5.safety/cushioning fuction

   The inside of cylinder set up an cushioning device in the end of stroke,it can absorb the juge inpact.
