Metallurgical oil cylinder CDH1 MT4 50/36-225

Specification: CDH1 MT4, 50mm Bore, 36mm Rod, 225mm Stroke, Trunnion Mount, Compact Metallurgical Grade Mill Type Hydraulic Cylinder 

CG series Hydraulic Cylinder, double acting mill cylinder, ISO 6022 hydraulic cylinder, heavy duty round body cylinder

MT4 trunnion mount with hardened steel pivot pins on both sides, pin diameter 25mm case depth 1.5mm, allowing cylinder to swing through 15-degree arc during load movement without side-loading rod bearings.

Trunnion block welded to barrel OD with full-penetration circumferential weld, post-weld stress relieved at 580 C for 2 hours, ultrasonic tested to EN 1714 acceptance class 2.

Compact bore 50mm with 225mm stroke, closed-center length under 500mm, fits into mill housing side-guard pockets where larger bore cylinders cannot be installed due to space constraints.

Piston fitted with glass-filled PTFE guide ring on full circumference, 3mm radial wall, prevents metal contact during trunnion pivot-induced barrel deflection under 49.1 kN full-load push.

Threaded rod clevis eye M24x2 standard, alternative rod end configurations available — spherical ball joint, cross-pin yoke, or metric fine thread stud — without changing cylinder envelope dimensions.

Lightweight design at 18 kg installed, one-person handling during mill maintenance shutdown, no lifting equipment required for removal and reinstallation in overhead positions.
