CD210G180/80-300 Rexroth Heavy Duty Hydraulic Cylinder

Product Overview

The CD210G, CD210B, CD210E and CDL1MF4 series (specific model CD210G180/80-300Z1X/01HCDM1-1A) are Bosch Rexroth CD210 series heavy-duty hydraulic oil cylinders featuring tie-rod modular construction for high-pressure industrial applications. Fully interchangeable with original Rexroth dimensions and interfaces, they install directly as drop-in replacements 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 them ideal for systems requiring high push/pull force and precise control.

Key Technical Advantages

• Heavy-duty modular construction: Tie-rod design facilitates maintenance, provides high rigidity and reliable sealing, supporting working pressures up to 210 bar.
• Full interchangeability: Manufactured to exact Bosch Rexroth CD210 original dimensions and mounting interfaces for true drop-in replacement, minimizing downtime.
• Precision machining and sealing system: High-precision cylinder tube and 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, metallurgical equipment, injection molding machines, die-casting machines, machine tools, 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 system filtration to ISO 4406 20/18/15. Avoid over-pressure or over-stroke operation. When replacing seals, use OEM or equivalent parts. For long-term storage, protect the piston rod with anti-rust oil.
