Feature: 1. The nitrogen gas spring 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. The initial spring pressure of the 750 series nitrogen gas spring is 7400N, the stroke is long, and the work is stable. 3. The nitrogen gas spring piston rod has high hardness after fine processing, and the surface roughness is about Ra0.02um 4. Made of alloy material and adopts integral cutting and forming process, which is safer and more reliable than pipe welding. 5. The cylinder body diameter of the nitrogen gas spring is 45.2mm, the plunger diameter is 25mm, the size is standard. Specification: Item Type: Nitrogen Gas Spring Material: Alloy Purpose: Die compression nitrogen cylinder Cylinder Diameter: Approx. 45.2mm / 1.8in Plunger Diameter: Approx. 25mm / 1in. Package List: 1 x Nitrogen Gas Spring1 x Storage Box Note: 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.
