Rexroth CDH1 Cylinder | CDH1MT4/80/56/1200 | CDH1MP5/80/56/380 | Long Stroke 1200mm

CDH1 Series Heavy-Duty Pull/Push Rod Hydraulic Cylinders

Product Overview:

The CDH1 series represents a premier line of tie-rod high-pressure cylinders engineered for 2026 heavy-duty construction machinery, metallurgical equipment, and automated presses. This collection highlights the core models ranging from the standard CDH1MP5/80/56/380 to the extra-long CDH1MT4/80/56/1200. With $25\text{ MPa}$ reliability, superior lateral load handling, and precision trunnion positioning, it is the professional choice for industrial power systems.

Core Model Specifications & Custom Parameters:

• CDH1MT4/80/56/1200A3X/B33CSDMZWWWAWWWW:

  • Specs: $80\text{mm}$ Bore, $56\text{mm}$ Rod, $1200\text{mm}$ Stroke.

  • Custom Dimension: $XV = 777\text{mm}$ (Distance from mounting face to trunnion center).

  • Design Series: A3X Advanced Series with CSD premium sealing.

• CDH1MP5-80-56-380A1X:

  • Specs: $80\text{mm}$ Bore, $56\text{mm}$ Rod, $380\text{mm}$ Stroke.

  • Mounting Style: MP5 (Rear Clevis with Spherical Bearing).

Key Technical Advantages:

• $1200\text{mm}$ Extra-Long Stroke Stability: Optimized for large-span operations, utilizing high-strength cold-drawn tubes and the A3X reinforced structure to ensure precise trajectory across the full stroke.

• MT4 Trunnion with Custom XV: The Intermediate Trunnion mount featuring the $XV = 777\text{mm}$ parameter guarantees seamless physical interchangeability and load balancing in complex mechanical structures.

• CSD Advanced Sealing Technology: The B33CSD composite sealing system offers an ultra-low friction coefficient and extreme wear resistance, preventing internal bypass and “stick-slip” motion in long-stroke cycles.

• $56\text{mm}$ Reinforced Rod: Induction-hardened and hard-chrome plated, providing massive resistance against bending loads and exceptional corrosion protection.

• Versatile Pull/Push Capability: Engineered for consistent performance as either a push or pull rod, ensuring stable power transition under high-pressure cycles.

Detailed Technical Specifications:

• Nominal Pressure: $25\text{ MPa}$ ($250\text{ bar}$).

• Bore/Rod Sizes: $80 / 56 \text{ mm}$.

• Stroke Range: $380\text{ mm}$ and $1200\text{ mm}$.

• Mounting Styles: MT4 (Intermediate Trunnion) / MP5 (Rear Clevis).

• XV Parameter: Customized $777\text{ mm}$.
