JW CYLINDER LIMITED delivers high-pressure hydraulic cylinders (up to 700 bar) designed for durability and safety. Our custom-engineered solutions meet rigorous international standards (ABS, DNV, Lloyd’s) and cater to industries like marine, mining, and heavy machinery.

2. Key Features & Specifications

Compatibility: HM anti-wear hydraulic oil (ISO VG 46-68 recommended)

Maximum Pressure: 700 bar (10,000+ PSI)

Materials: High-strength alloy barrels, hardened piston rods

Seals: Premium HALLITE® seals (standard) or custom kits

3. Installation & Operation Guidelines

Pre-Installation Checks

• Verify hydraulic system pressure matches cylinder ratings.
• Use HM anti-wear hydraulic oil (filtered to NAS 1638 Class 8) to prevent seal damage.
• Purge air via low-pressure cycling (≥ starting pressure) before full operation.

Critical Installation Steps

• Align piston rod with cylinder head/trunnion to ensure straightness (prevents filter plate sludge buildup and rod deflection).
• Secure ports with combined gaskets to eliminate leaks.

4. Maintenance & Safety Protocols

Routine Maintenance

• Oil Quality: Monitor viscosity and contamination (replace/filter every 6,000 hours).
• Seal Replacement: Schedule every 6,000 operational hours or as per HALLITE® guidelines.
• Idle Cylinders: Cycle monthly to prevent surface rust.

Troubleshooting

• Leakage/Performance Issues: Replace seals, inspect rod alignment, and verify oil cleanliness.
• Emergency Repairs: Depressurize system, block ports, and disassemble only when piston rod is fully retracted.
