80MF3MMARN14M600 Rexroth High Pressure Hydraulic Cylinder

Product Overview

The 80MF3, 63JJ, 40CC, 50CB, 40CJJ, CDL2MF3 and 50DHM series (specific model 80MF3MMARN14M600M1) is a high-pressure double-acting hydraulic oil cylinder featuring heavy-duty tie-rod or welded construction for demanding industrial applications. Fully interchangeable with Bosch Rexroth CDL2 / Parker HMI series dimensions and interfaces (MF3 round flange mounting etc.), it installs directly as a drop-in replacement without modifying mounts or plumbing. Every unit undergoes 100% simulated operating condition testing to ensure reliable performance under high pressure, vibration and continuous loading, making it ideal for systems requiring high push/pull force and precise control.

Key Technical Advantages

• High-pressure high-strength construction: Premium steel and precision design support working pressures up to 250 bar, delivering excellent fatigue resistance and structural rigidity.
• Full interchangeability: Manufactured to exact Rexroth CDL2 / Parker HMI series dimensions and mounting interfaces for true drop-in replacement, minimizing downtime.
• Precision machining and sealing system: Honed cylinder bore and hard-chrome plated piston rod combined with high-performance seals reduce internal leakage, improve volumetric efficiency and extend service life.
• Rigorous quality control: Every cylinder undergoes 100% simulated duty-cycle testing to verify pressure integrity, leakage and fatigue performance for long-term industrial reliability.

Application Areas

Construction machinery, injection molding machines, die-casting machines, metallurgical equipment, machine tool fixtures, test stands, material handling equipment, and industrial hydraulic systems requiring high-pressure double-acting push/pull control. Especially suitable for OEM equipment and retrofit projects.

Expert Maintenance Tips

Verify mounting surface flatness and alignment before installation to avoid side loading. Connect ports correctly and bleed air from the system. Regularly inspect seals and piston rod surface for wear. Use clean, compatible hydraulic fluid and maintain proper system filtration. Avoid over-pressure or over-stroke operation. When replacing seals, use OEM or equivalent parts and tighten to specified torque. For long-term storage, protect the piston rod with anti-rust oil.
