The cylinder body is made of high-tensile seamless alloy steel with strong compression and anti-deformation capacity. The piston rod undergoes induction hardening and hard chrome plating to resist wear, corrosion and impact. High-performance sealing parts effectively prevent oil leakage, ensuring stable operation within -20℃ to +85℃. All products pass leakage, fatigue and dimensional tests before delivery.
