SI standard cylinder, the piston seal adopts two NBR+PA material Y-shaped one-way seal structure, which has compensation function, long life and low starting pressure.
1. The cylinder conforms to the ISO15552 standard cylinder.
2. The shaft seal material is made of PU material, which has the characteristics of high strength, good toughness, wear resistance, oil resistance, and aging resistance.
3. The front and rear end covers of the cylinder have a buffer adjustment function, which makes the cylinder piston run smoothly at both ends without impact.
