Specifications: Material: alloy + stainless steel Colour: Black Stroke: 20mm Max. absorbed energy: 22 Nm Energy absorption: 35000 Nm/h Effective Weight: 10-160WE(KG) Permissible Speed: 0.8-3m/s Working temperature: -10~80℃ Thread: M14 Length: Approx. 12.6 cm/4.96 inch Weight approx. 106g Included: 1 x oil pressure shock absorber Note: Please aim the impact body at the center of the shaft. Do not remove the front cap before use, as removing the cap will lengthen the plunger rod and hit the bottom, which may cause the bottom to break. It is strictly forbidden to spray paint on the pipe teeth and shaft hub, otherwise it will affect the heat dissipation effect and cause oil leakage. Avoid rust and other foreign matter on the piston rod. If two or more anti-vibration mounts are installed on the same side, please check the synchronization. For safety reasons, do not disassemble to use. Please note that the new and old type of this product will be shipped at random. Before ordering, make sure you don't mind. Package List
