Metallurgical oil cylinder CDH1 MP3 80/45-230

MP3 plain clevis base end with hardened pin bore diameter 40mm H8, fitted with sintered bronze PTFE-lined bushing, service life 500000+ full-stroke cycles before bushing replacement required on pin joint.

Clevis pin retained via cross-bolt and lock plate, prevents pin walk-out under bi-directional loading common in articulated mill mechanisms, no external retaining ring failure mode.

Rod end threaded M36x2 with lock nut and spherical rod eye option, eye bore 30mm, angular misalignment capacity 3 degrees for push-pull linkages without side-loading the rod seal.

Cylinder tube internal surface roller-burnished after honing, surface hardness increased 15-20 HB by cold work, improving wear resistance for mineral oil with suspended particulate in mill central hydraulic systems.

Compact envelope: retracted length 480mm for 230mm stroke, allows installation in mill-side positions with limited clearance between roll chocks and housing windows.

Bleed port positioned radially at gland for trapped air evacuation during commissioning, eliminates spongy stroke response without inverting cylinder during installation.

Applied in rolling mill pass line adjustment, furnace charging door lift, continuous casting dummy bar disconnect, scale breaker roll positioning and cooling bed transfer arm actuation.
