Rexroth CD210 Cylinder | CD210F80/45-300 | CD210B80/56-450 | ISO 6022 Hydraulic

CD210 Series Heavy-Duty Industrial Hydraulic Cylinders

Product Overview:

The CD210 series stands as a premier line of high-performance heavy-duty cylinders conforming to ISO 6022 and DIN 24333 standards. Engineered for the demanding metallurgical, forging, and heavy machinery sectors of 2026, these cylinders are optimized for $21 \text{ MPa}$ high-pressure operations. This range highlights F (Head Rectangular Flange) and B (Head Round Flange) mounting styles, delivering exceptional pressure stability and extended service life.

Core Model Specifications:

• CD210F80/45-300Z1X/01CCDM1-1T:

  • Specs: $80\text{mm}$ Bore, $45\text{mm}$ Rod, $300\text{mm}$ Stroke.

  • Mount: F (Head Rectangular Flange) for high-thrust axial stability.

  • Configuration: Z1X Series with CDM1 grade sealing.

• CD210B80/56-450Z1X/01HFDM4-4T:

  • Specs: $80\text{mm}$ Bore, $56\text{mm}$ Rod, $450\text{mm}$ Stroke.

  • Mount: B (Head Round Flange) for superior load distribution.

  • Configuration: Features HFD thermal-resistant/low-friction seal group.

Key Technical Advantages:

• 210 bar Heavy-Duty Capacity: Constructed with reinforced thick-walled barrels and heavy-duty bolted/welded designs, ensuring zero deformation under intensive 2026 pressure pulse cycles.

• ISO 6022 Compliance: Offers global interchangeability, allowing $100\%$ physical replacement for original Rexroth units or other ISO standard cylinders, reducing maintenance overhead.

• Optimized Rod Ratios: Available in $45\text{mm}$ and $56\text{mm}$ rod diameters, enabling precise selection based on differential ratios, retraction speeds, and bending resistance.

• Advanced Sealing (CDM/HFD): Utilizes low-friction composite seals to prevent internal bypass leakage under peak pressure while providing excellent contamination resistance and eliminating “stick-slip” motion.

• Integrated Precision Cushioning: Features high-performance adjustable cushioning to absorb kinetic energy at stroke ends, significantly reducing mechanical shock and operating noise.

Detailed Technical Specifications:

• Nominal Pressure: $21 \text{ MPa}$ ($210 \text{ bar}$).

• Piston Ø: $80 \text{ mm}$.

• Rod Ø: $45 \text{ mm}$ / $56 \text{ mm}$.

• Stroke Range: From $300 \text{ mm}$ to $450 \text{ mm}$.

• Seal Material: High-grade Nitrile (NBR) or Viton (FKM).
