Feature:1. There are C shape notch on the upper and U shape notch on the bottom with M8 screw holes, which is easy to install.2. There is an inflation port on the side of the gas spring cylinder, which can be used for pipe connection system.3. The initial spring pressure of 2400 series nitrogen gas spring is 24000N, which is small in size and long in working stroke.4. The piston rod has high hardness after special processing of fine processing, and the roughness reaches about Ra0.02um.5. The cylinder diameter of the nitrogen gas spring is 75.2mm, and the plunger diameter is 45mm, which makes the installation and use more precise.Specification:Item Type: Nitrogen Gas SpringMaterial: AlloyPurpose: Die compression nitrogen cylinderCylinder Diameter: Approx. 75.2mm / 3inPlunger Diameter: Approx. 45mm / 1.8in.Package List:1 x Nitrogen Gas SpringNote:1. Do not use the nitrogen gas spring plunger rod for fixing, and the threaded hole at the end of the piston rod cannot be used as a lifting hole for lifting.2. Do not modify the following aspects of the nitrogen gas spring:(1)Drill holes on the cylinder block of the nitrogen gas spring, the sealing ring, etc.(2)The piston rod is shortened in order to reduce the stroke(3)Do not perform other processing on the nitrogen gas spring and its accessories3. Do not use nitrogen gas springs for purposes outside the scope of product catalog specifications.4. Do not allow the ammonia gas spring to return freely after being compressed, as this will cause damage to the internal structure.
