Rexroth CDT3 Cylinder | CDT3MT4/80/45/800 | CDT3MS2/63/45/240 | ISO 6020-2 Hydraulic

CDT3 Series Heavy-Duty Tie-Rod Hydraulic Cylinders

Product Overview:

The CDT3 series represents premier tie-rod cylinders conforming to ISO 6020-2 standards, engineered for the high-precision automation, machine tools, and pressing equipment of 2026. This range features the CDT3MT4 (with an $800\text{mm}$ long stroke and trunnion mount) and the compact CDT3MS2 (with foot mounting). With a nominal pressure rating of $16 \text{ MPa}$ ($160 \text{ bar}$) and highly modular configurations, the CDT3 series is a global leader in industrial actuation.

Core Model Specifications:

• CDT3MT4/80/45/800Z20/B22HDUTWW:

  • Specs: $80\text{mm}$ Bore, $45\text{mm}$ Rod, $800\text{mm}$ Stroke.

  • Mount: MT4 (Intermediate Trunnion).

  • Custom Dim: $361.0\text{mm}$ specific interface positioning.

  • Sealing: HDU-grade advanced seals for superior self-lubrication.

• CDT3MS2/63/45/240Z30/B11HHUMW:

  • Specs: $63\text{mm}$ Bore, $45\text{mm}$ Rod, $240\text{mm}$ Stroke.

  • Mount: MS2 (Side Lugs/Foot Mount) for robust surface support.

Key Technical Advantages:

• Global ISO 6020-2 Interchangeability: Manufactured to strict international standards, ensuring $100\%$ physical replacement for original Rexroth units or other standard ISO cylinders.

• MT4 Trunnion Dynamic Compensation: The intermediate trunnion on the CDT3MT4 allows the cylinder to pivot slightly, effectively absorbing lateral loads in $800\text{mm}$ long-stroke applications.

• HHU/HDU Sealing Technology: Features the latest composite seal groups with ultra-low breakaway friction. This prevents internal bypass and eliminates “stick-slip” motion at low speeds.

• High-Strength Tie-Rod Integrity: The heat-treated four-tie-rod structure maintains perfect linearity and extreme fatigue life under continuous $160 \text{ bar}$ industrial cycles.

• Precision Chromed Rods: High surface hardness with excellent corrosion resistance, designed for the diverse shop floor environments of 2026.
