Air return Rate control adopts the fully closed structure, action accurate and uniform, the piston rod can be any stops on the stroke, realized efficient feed function step by step, improved the machining precision. When the 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 feed control more convenient, at the same time under the condition of temperature difference will not affect the steady speed function.;
Features: installation easily, maintenance-free, after the rate control piston rod’s load unloading, piston rod remain stagnant in situ, only provide compressed air to the piston rod is returned, it can be carried out step by step control
Buffer body: high strength hardened steel, surface black finish;
The rate control piston rod: high hardness of stainless steel;
Piston: wear-resisting copper;
Suitable for working temperature range in -40 ℃to +80℃;

Matters needing attention:

1.Keep the heavy duty shock absorbers piston rod clean, do not have iron foreign body

2.No painting in heavy duty shock absorbers tube teeth and the axis, so as not to affect the cooling effect and leak case;

3.Pay attention to the strength of fixed plate and eccentric angle when assembly

4.If you have the cushion cap product, do not unload cushion cap by self for using, this will seriously affect the service life
