hydraulic cylinder fabrication hydraulic telescopic cylinder

Specification: Super Heavy Duty Mill Cylinder / CDH1 MP5 280/200 / ISO 6022 / Massive Hydraulic Actuator

CD Series Cylinder, Differential Mill Cylinder, Round Body Cylinder, Bolted Cylinder, Fast Speed Cylinder

Heavy-Duty Engineering: Specifically designed for ultra-large loads in steel mills and mining environments. 280mm Bore / 200mm Rod / 1150mm Stroke.

Pressure Rating: Nominal working pressure 250 Bar (25 MPa); Static test pressure up to 375 Bar. High peak-load resistance.

Standard Compliance: Manufactured to ISO 6022 and DIN 24333 standards. 100% interchangeable with large-scale Rexroth CDH1 series.

Mounting Style: MP5 Rear Clevis with integrated high-load spherical bearings. Accommodates angular misalignment and prevents side-loading on the 200mm rod.

Advanced Sealing: Features multi-lip high-pressure sealing systems with specialized bronze-filled PTFE wear rings to handle extreme frequency and heavy vibrations.

Rod Quality: Induction-hardened C45 steel rod with precision hard chrome plating (30-50μm thickness, surface finish Ra ≤ 0.4μm).

Maintenance Friendly: Robust bolted flange construction allows for straightforward on-site maintenance without specialized heavy machinery removal.
