50DHMIRN14MC185 Parker High Pressure Hydraulic Cylinder

Product Overview

The 50DHMIRN14MC185.00M113363JJ (50DHM series) is a high-pressure double-acting hydraulic oil cylinder featuring high-strength tie-rod or compact construction for demanding industrial applications. Fully interchangeable with Parker HMI/DHM series dimensions and interfaces (50 mm bore, M14 ports, JJ 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 tie-rod design support working pressures up to 210 bar, delivering excellent fatigue resistance and structural rigidity.
• Full interchangeability: Manufactured to exact Parker HMI/DHM 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 check tie-rod nut torque, seal condition 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.
