Guoyue Hydraulics CDH1 MP5 Mill-Type Double-Acting Hydraulic Cylinder — 250mm Bore × 180mm Rod × 350mm Stroke, Rexroth CDH1 Compatible, 25 MPa
Specification: CDH1 Mill-Type Cylinder, 250mm Bore, Double-Acting, Trunnion Mount, Rexroth Compatible (mill type hydraulic cylinder, CDH1 cylinder, heavy duty cylinder, 250mm bore cylinder, trunnion mount cylinder)
Built to ISO 6020/6022 and DIN 24333 dimensional standards with 250 mm bore, 180 mm piston rod, and 350 mm stroke. Cylinder barrel fabricated from 27SiMn / ST52-3 honed seamless tube, roller-burnished to Ra ≤ 0.2 μm internal finish. Multi-segment bolted flange construction allows modular reconfiguration.
Piston rod in CK45 / 42CrMo4 alloy steel, induction hardened to HRC 52–58, hard chrome plated to 25–40 μm thickness. Surface hardness HV 850–1050 with 96+ hour salt spray resistance per ASTM B117. Rod wiper and rod seal housing separated for staged contamination control.
Sealing system using Parker / Merkel profile geometry: PTFE step-cut primary seal with NBR energizer, paired with polyurethane buffer ring and double-lip rod wiper. Static seals: O-ring + PTFE backup ring per ISO 3601. End cushioning: adjustable needle valve type at both head and cap ends for controlled deceleration.
MP5 trunnion mount located at cylinder centerline, machined from forged 42CrMo steel with hardened bearing surface. Rod end fitted with spherical plain bearing (self-aligning, maintenance-free type with grease nipple) to absorb misalignment. Base end uses clevis with hardened steel bushing, secured to barrel via high-tensile 12.9 grade bolts.
Full dimensional interchangeability with Rexroth CDH1 MP5 series. Bolt pattern, port locations, and mounting interface match OEM specifications. Accepts standard Rexroth CDH1 seal kits and spare parts.
Each unit hydrostatically tested at 35 MPa (1.4× rated) for 5 minutes, followed by full-stroke cycling at 0.5 MPa to verify seal integrity, side load tolerance, and cushioning consistency. Inspection certificate and material traceability report included.
Designed for: steel mill AGC (Automatic Gauge Control) cylinders, heavy-duty forging press main ram, continuous casting machine mold oscillation, mining shovel boom actuation, and general mill-type applications requiring sustained 250 Bar operation with high side load resistance.
Our hydraulic cylinders meet rigorous quality standards and are certified by leading classification societies including ABS, Lloyds, and SGS.
Our comprehensive technical support includes troubleshooting guidance, maintenance advice, and direct access to specialized engineers. We provide installation assistance, calibration services, and training resources to ensure optimal performance and safe operation.
Each hydraulic cylinder is carefully packaged in protective materials with clear handling instructions. Units are securely packed in wooden packaging to prevent damage during transportation.
