CDL2MP5/50/28/680 Rexroth Mill Type Hydraulic Cylinder

Product Overview

The CDL1MP5, CDL1MT4, CDL2MP5 and CDL2MF3 series (specific model CDL2MP5/50/28/680 D10/B11CHUMWW) are Bosch Rexroth CDL2 series mill-type heavy-duty hydraulic oil cylinders featuring welded construction and short overall length 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 short-length construction: Welded mill-type design provides high rigidity and compact installation dimensions, ideal for space-constrained high-pressure applications.
• Full interchangeability: Manufactured to exact Bosch Rexroth CDL2 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, injection molding machines, die-casting machines, metallurgical equipment, 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 inspect seals 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.
