Actuating Cylinder Auxiliary Open Mold Cylinder
Specification: CGH1 MT4, 110mm Bore, 70mm Through Rod, 220mm Stroke, Trunnion Mount Double Rod Synchronous Cylinder
CD Series Cylinder, Differential Mill Cylinder, Round Body Cylinder, Bolted Cylinder, Fast Speed Cylinder
CGH1 through-rod design with identical 70mm rod diameter both ends eliminates the force differential of single rod cylinders, both chambers output 141.4 kN at 250 Bar without requiring a flow divider valve in the circuit.
Key Features
- MT4 trunnion mount with split clamp ring retention on the barrel, trunnion pins 40mm case-hardened, allowing the entire cylinder body to pivot freely while maintaining equal push-pull force regardless of pivot angle
- Both rod ends accessible for position feedback — linear transducer can be mounted on either side without relocating the cylinder, critical for closed-loop synchronization of dual-cylinder mill mechanisms
- Piston centered by two PTFE wear rings spaced 65mm apart on the piston body, maintaining rod concentricity through the trunnion pivot range, seal contact pressure even across 360 degrees
- Identical seal kits for both head and cap ends reduce spare parts inventory by 50% compared to single rod cylinders, single maintenance procedure covers both ends
- Trunnion clamping bolts M16 grade 12.9 torque-to-yield specification 210 Nm, split ring design allows barrel rotation for port alignment during installation without welding or re-machining the mount pad
Applications
Applied in continuous casting dummy bar chain tension cylinders, mandrel locking on down-coiler, synchronized mold oscillation drive, strip edge guide positioning and furnace pusher mechanisms requiring equal force in both stroke directions.
