Precision Engineered CDH1 MP5 140-90-300 Self-aligning Spherical Clevis Base Mount Chrome Plated Piston Rod Metallurgical Hydraulic Cylinder for Steel

Specification: CDH1 MP5, 140mm Bore, 90mm Rod, 300mm Stroke, Self-aligning Clevis Base Mount, Metallurgical Grade Mill Type Hydraulic Cylinder

MP5 spherical plain bearing at rod eye rated for 245 kN dynamic radial load per DIN ISO 12240-1, ±4-degree misalignment tolerance absorbs installation offset without transferring bending moment to the piston rod.
Mid-body intermediate trunnion pin arrangement supplements the base mount, distributing load path across two support points and reducing barrel deflection to under 0.15mm at full 384.8 kN push stroke.
Cylinder tube wall thickness 12mm on 140mm bore, hoop stress factor 3.5 at 250 Bar working pressure, autofrettage-treated for enhanced fatigue life under pulsating mill duty cycles.
Piston seal groove machined to accept twin-lip elastomer element with anti-extrusion PTFE backup on both sides, zero measurable leakage across 100 hour pressure hold test at rated pressure.
Gland retention by segmented split-ring collar rather than external threaded lock nut, allowing gland removal without disturbing pipework connections, service time reduced from 4 hours to 45 minutes.
Rod protector boot mounting groove machined on rod barrel exterior, accepts standard bellows boot for exposed installations where mill scale spray or hot particles contact the rod stroke area.
Applied in ladle turret slew arm actuation, tundish car transfer positioning, mold width adjustment on continuous casters, roll changer cylinder duty and blast furnace tuyere plug drive on hot metal charge floor equipment.
