How to choice the hydraulic cylinder’s condition ?
Double-acting series cylinders with hydraulic check valve.
Whether need working at narrow space,
Make sure the fuel capacity of hydraulic cylinder,
Whether need several cylinders are used together,
Whether need hydraulic cylinder with partial load work,
Whether need several hydraulic cylinders are working together,
Whether need keep the loading with long time,
Fuel capacity (cm)=The active area of cylinder X the stroke of cylinder (cm).
The hollow plunger is designed to produce thrust and be used for pulling force. The cylinder body has outer ring thread, plunger has internal thread, and the bottom has installation hole, which makes it be widely used.
The top and plunger are equipped with alloy guide sleeve to absorb bias force and prolong the service life of hydraulic cylinder.
The top of the cylinder is equipped with a dust ring.
Single action and spring back, are much more convenient to use.
