Feature:1. The cylinder body has a C shape notch on the upper and a 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 also be used for pipe connection systems.3. The initial spring pressure of 4200 series nitrogen gas spring is 42000N, with long stroke and stable operation.4. With piston rod, the hardness is high after fine machining, and the surface roughness reaches about Ra0.02um.5. Made of alloy material and adopts integral cutting and forming process, which is safer and more reliable than pipe welding.Specification:Item Type: Nitrogen Gas SpringMaterial: AlloyPurpose: Mold compression nitrogen gas cylinderCylinder Diameter: Approx. 95.2mm / 3.7inPlunger Diameter: Approx. 60mm / 2.4in.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.
