Specification: Robot Arm Telescopic Cylinder / Heavy Duty Hydraulic Cylinder 125/70-3100 / Long Stroke Cylinder
Telescopic Hydraulic Cylinder,Multi Section Hydraulic Cylinders,Multi Stage Hydraulic Cylinder
Manufactured in accordance with ISO 6022 mounting dimensions and essential hydraulic safety standards.
Bore 125mm, Rod 70mm, Stroke 3100mm — extended overall length supports deep-reaching robotic arm applications.
Cylinder barrel in honed cold-drawn seamless steel tube, internal surface roughness Ra 0.2-0.4μm.
Piston rod in induction-hardened chrome-plated steel, chrome layer thickness 30-50μm, surface hardness HRC 50-55.
Working pressure rated at 250 Bar, test pressure 375 Bar.
Double-acting design with cushioning at both ends, reducing end-stroke impact and extending seal service life.
Sealing system: imported polyurethane (PU) + nitrile (NBR) combination rod & piston seals, with double dust wiper ring on rod side.
Both ends fitted with MP5-type spherical plain bearings, self-aligning angular compensation ±5°, reducing side-load damage risk.
Dual hydraulic oil ports with standard metric thread, compatible with common hydraulic fittings.
Telescopic cylinder body with intermediate guide rings positioned at each stage junction, ensuring concentric alignment throughout full stroke.
Blue PU topcoat over anti-rust primer, salt-spray tested to 200 hours for outdoor and industrial environments.
Interchangeable with Rexroth CD/CGH series and Parker HMI series mounting interfaces.
Typical application: industrial robot arm extension, automated loading/unloading systems, forging press manipulators, injection molding machine ejectors, scrap shear feeding mechanisms, and material handling gantry systems.
Custom bore/rod/stroke configurations available. Contact factory for drawing confirmation before order.
