50CDH Parker Heavy Duty Hydraulic Cylinder 210Bar

Product Overview

The 50CDH / 50CJJH Series Heavy-Duty Tie-Rod Hydraulic Cylinders (including precise configuration codes like 50CJJHMIRN39MC100.00M1133 and 50CDHMIRN34MC50.00M1144) are engineered for high-pressure, high-frequency, and severe industrial applications. Built in strict compliance with ISO 6020/2 and DIN 24336 standards, these cylinders match Parker OEM engineering specifications, offering 100% drop-in mechanical, hydraulic, and mounting interchangeability. Featuring precision roller-burnished seamless steel tubes and induction-hardened, hard-chrome-plated alloy steel piston rods, the 50CDH series delivers low friction, zero stick-slip, and exceptional seal durability under working pressures up to 210 bar. Every cylinder undergoes 100% factory bench testing under simulated full-stroke high-pressure conditions to ensure direct, reliable field replacement for original Parker actuators.

Technical Specifications 

• Full Model Code: 50CDH / 50CJJH (Specific codes: 50CJJHMIRN39MC100.00M1133, 50CDHMIRN34MC50.00M1144)

• Bore & Rod Diameters: Bore 50 mm / Rod 22 mm, 28 mm, or 36 mm (Depending on model code)

• Nominal Operating Pressure: 210 bar (21 MPa)

• Peak Test Pressure: 250 bar (25 MPa)

• Mounting Style: ISO 6020/2 mounting configurations (e.g., intermediate trunnion ME/MP/MT, front/rear flange)

• Stroke Lengths: 50.00 mm / 100.00 mm and custom stroke options

• Fluid & Velocity Range: Standard mineral hydraulic oils; operating speeds up to 0.5 m/s (up to 2.0 m/s with low-friction seals)

• Operating Temperature: -20°C to +80°C (High-temperature Viton seals available)

• Net Weight: Approx. 8.5 kg – 14.5 kg (Varies by stroke and mounting)

Key Technical Advantages

• 100% Drop-In OEM Interchangeability: Mounting threads, pin sizes, port dimensions (BSPP/SAE), and overall envelope lengths match Parker 210 bar 50CDH/50CJJH standards for seamless plug-and-play installation.

• Honed Barrel & Hardened Piston Rod: Cylinder barrels feature precision roller-burnished inner walls ($Ra < 0.2\ \mu\text{m}$). Piston rods are induction-hardened and hard-chrome-plated ($\ge 25\ \mu\text{m}$ coating thickness) to resist scratching and corrosion.

• Multi-Stage Sealing System: Equipped with polyurethane main seals, double-lip wiper rings, and anti-extrusion step-seals to eliminate creep, minimize friction, and maintain zero external leakage under pressure surges.

• 100% High-Pressure Bench Tested: Every unit is validated on automated test benches at 1.5 times nominal pressure ($> 315\ \text{bar}$) for holding integrity, cushioning performance, and internal leakage verification before shipment.

Application Areas

• Metallurgy & Steel Production: Rolling mill guide adjustments, converter tilting cylinders, and continuous caster press controls.

• Plastics & Mold Machinery: Injection molding core-pulling cylinders, blow molding clamping units, and ejector mechanisms.

• Heavy Machine Tools & Presses: Modular machine tool clamping, high-tonnage press auxiliary cylinders, and hydraulic press brakes.

• Marine & Construction Engineering: Ship roll stabilizers, specialized lifting equipment, and steering hydraulic circuits.

Expert Maintenance Tips

• Ensure Precise Axial Alignment: Align the piston rod axis accurately with the load path during installation. Avoid excessive side loads to prevent scoring on the piston rod and uneven wear on guide bushings.

• Maintain High Fluid Cleanliness: Keep system hydraulic fluid clean to ISO 4406 18/16/13 (NAS Class 8) or cleaner. Regularly replace return line filter cartridges to prevent metallic debris from damaging the cylinder bore and seals.

• Perform Air Bleeding & Cushion Tuning: Bleed air using the end-cap screws at low pressure during initial startup until movement is smooth. For cushioned models, adjust the end-cushion needle valves to ensure smooth deceleration without metallic impact at end strokes.
