Custom Flanged Mill-Duty Hydraulic Cylinder for Steel Mill Equipment
The APEX-CMDC flanged mill-duty hydraulic cylinder is engineered for demanding steel mill applications such as rolling mills and continuous casting machines. Constructed with heavy-wall precision-honed steel barrel and high-strength alloy steel piston rod, it delivers robust performance under high pressure, high-frequency cycling, and harsh environmental conditions. With a bore range of 50–320 mm and working pressure up to 250 bar, these cylinders provide reliable force for pressing, clamping, and positioning tasks. Flanged mounting ensures high structural rigidity and stable alignment. The replaceable gland design simplifies maintenance, while optional position sensors enable precise control in automated production lines.
Key Selling Points
Flanged or threaded-head construction provides high structural rigidity for fixed industrial machinery, minimizing deflection under heavy loads.
Replaceable gland design simplifies seal replacement and planned maintenance, reducing downtime and maintenance costs.
Optional adjustable end-of-stroke cushioning controls high-inertia loads near stroke end, protecting equipment and improving safety.
Large bearing areas and optional stop tubes improve stability on long-stroke applications, ensuring smooth operation.
Optional position sensors (proximity switches, linear transducers) enable accurate position monitoring for automated steel processing lines.
High-temperature seals and metal scrapers are available for harsh environments with radiant heat, scale, and dust, enhancing durability.

Materials and Structure
The cylinder barrel is made from heavy-wall precision-honed seamless steel tube. The piston rod is high-strength alloy steel with hard chrome or induction-hardened chrome surface treatment. Piston, head, and base are high-strength forged or machined steel. Flanges are high-strength forged or machined steel. Wear rings are high-load reinforced polymer, phenolic composite, or bronze guide material. Primary seals are high-pressure polyurethane, PTFE composite, or industrial sealing system; static seals are NBR or FKM.
Applications
Ideal for steel mills, metallurgical equipment, aluminum processing, rolling mills, continuous casting equipment, industrial hydraulic presses, forging equipment, and foundry equipment. Common functions include pressing, clamping, lifting, tilting, positioning, and roll-gap adjustment in heavy industrial production lines.
Customization
We customize bore, stroke, rod diameter, ports, mountings, cushioning, sensors, and surface protection based on your drawings or verified samples. Options include water-glycol-compatible seals, protective boots, and water cooling for high-temperature environments. Material, welding, inspection, and pressure-test documentation can be supplied per OEM requirements.
FAQ
