Rexroth CDH2 Cylinder | CDH2MT4/100/63/275 | Trunnion Mount | XV=280mm Hydraulic Cylinder

CDH2 Series Heavy-Duty Trunnion Mount Hydraulic Cylinder

Product Overview:

The CDH2 series represents a premier line of tie-rod hydraulic cylinders engineered for the demanding metallurgical, heavy machinery, and automated press applications of 2026. This model, CDH2MT4/100/63/275A3X, features an intermediate trunnion mount with a specialized $XV = 280\text{mm}$ positioning parameter. With a nominal pressure rating of $25 \sim 31.5 \text{ MPa}$, it serves as a robust core for heavy-duty power transmission.

Core Model Specifications & Parameters:

• Full Code: CDH2MT4/100/63/275A3X/B11CFEM ZWFWWWWWC

• Custom Dimension: $XV = 280\text{mm}$ (Distance from mounting face to trunnion center).

• Specifications: $100\text{mm}$ Bore / $63\text{mm}$ Rod / $275\text{mm}$ Stroke.

Key Technical Advantages:

• MT4 Intermediate Trunnion Mount: The pivoting trunnion design allows the cylinder to oscillate during operation, compensating for axial misalignment. The custom $XV = 280\text{mm}$ ensures seamless integration with existing machine bases.

• CFEM Advanced Sealing: Equipped with the B11CFEM composite sealing system, offering low friction and extreme wear resistance. It ensures zero leakage and eliminates “stick-slip” motion during intensive 2026 industrial cycles.

• Series 3X Optimized Design: Built to the latest Rexroth industrial standards, the reinforced structure handles peak shock loads and high-cycle fatigue with ease.

• Precision Hardened Rod: The $63\text{mm}$ rod is induction-hardened and hard-chrome plated for superior surface hardness, corrosion resistance, and protection against mechanical scratches.

• Adjustable Cushioning: Integrated end-position cushioning absorbs kinetic energy, significantly reducing mechanical impact noise and extending equipment longevity.

Detailed Technical Specifications:

• Nominal Pressure: $25 \text{ MPa} (250 \text{ bar})$ to $31.5 \text{ MPa}$.

• Mounting Style: MT4 (Intermediate Trunnion).

• Stroke: $275 \text{ mm}$.

• Compatible Mediums: Mineral oils, synthetic fluids, and water-glycols.
