CDH1 MF3 Long Stroke Hydraulic Cylinder — 70mm Bore × 50mm Rod × 2040mm Stroke, ISO 6022 Mill Type, 250 Bar

Heavy duty hydraulic cylinder for marine applications 
Specification: CDH1 MF3, 70mm Bore, 50mm Rod, 2040mm Stroke, Long Stroke Mill Type Hydraulic Cylinder 
Manufactured to ISO 6022 / DIN ISO 3320 dimensional and mounting standards, Rexroth CDH1 series compatible.
Bore 70 mm × Rod 50 mm × Stroke 2040 mm, double-acting differential cylinder, nominal pressure 250 Bar (static proof pressure 375 Bar).
MF3 mounting style — round flange at head end, designed for flange-face mounting; six standard mounting options available across CDH1 series (MF3 / MF4 / MP3 / MP5 / MT4 / MS2).
Piston rod: induction-hardened, chrome-plated 30–50 μm, surface roughness Ra ≤ 0.2 μm, corrosion-resistant to ISO 9227 (NSS ≥ 96 h), surface hardness ≥ 55 HRC.
Long stroke design — 2040 mm stroke length, piston rod buckling verified per Euler buckling calculation at maximum rated pressure 250 Bar; suitable for extended linear motion applications.
Cylinder tube: precision-honed seamless cold-drawn steel, honed to H8 tolerance, internal surface roughness Ra ≤ 0.4 μm.
Seal system: polyurethane/polytetrafluoroethylene (PU/PTFE) step seal + wiper, low friction, extended service life. End position cushioning with throttle valve (standard "E" option), adjustable on both ends.
Threaded piston rod end with locking nut; Rexroth interchangeability — direct drop-in replacement for OEM Rexroth CDH1 MF3 cylinders.
Port size: per ISO 6022 standard flange connection. Bleeding valve fitted (90° offset relative to line connection, clockwise when viewing piston rod).
Operating temperature range: −20 °C to +80 °C (NBR seals), viscosity 2.8–380 mm²/s (ISO VG 32 – 68 mineral oil recommended).
Application: long-stroke press cylinder, injection molding machine clamping/ejection, die-casting machine, material handling lift, extrusion press, and general linear actuation requiring extended stroke.
