The cylinder body uses high-tensile seamless alloy steel for solid compression and anti-deformation performance. The piston rod is treated with induction hardening and hard chrome plating to resist wear and impact. Premium high-pressure seals prevent oil leakage, supporting stable operation at -20℃ to +85℃. All units pass strict leakage, fatigue and dimensional tests before delivery.
