Hydraulic speed controls adopts the fully closed structure, action accurate and uniform,. When the hydro check piston rod is pressed, hydraulic oil under pressure outflow from the adjustable overflow oil hole, provides the whole stroke with a constant feed control precision. By rotating the end of the outer shell outer adjustment knob can realize the adjustment of the feed speed. Fixed aluminum base makes it easier to install and adjust knob to velocity and feed controllers more convenient, at the same time under the condition of temperature difference will not affect the steady speed function.
Features: installation easily, maintenance-free, when the velocity and feed controllers piston rod’s load unloading, piston rod returning automatically.
hydraulic speed controls body: high strength hardened steel, surface black finish
The piston rod: high hardness of stainless steel;
Piston: wear-resisting for copper;
Suitable for working temperature range in -40℃to +80℃;
Matters needing attention:
1.Pay attention to the strength of fixed plate and eccentric angle when assembly;
2.No painting in tube teeth and the axis, so as not to affect the cooling effect and leak case;
3.Keep the hydro check piston rod clean, do not have iron foreign body;
4.If you have the cushion cap product, do not unload cushion cap by self for using, this will seriously affect the service life;
