Mining Shovel Hydraulic Cylinder – Custom Heavy-Duty High-Pressure Series

Designed for the extreme demands of hydraulic mining shovels, excavators, and loaders, our APEX-CHDC Series cylinders deliver high force, superior durability, and reliable operation in the harshest environments.

Key Selling Points

• High-Pressure, High-Load Design: Engineered to withstand peak loads and continuous high-pressure operation typical of mining equipment.
• Customizable Bore & Stroke: Bore diameter and stroke are tailored to your required force, space envelope, and equipment movement.
• Heavy-Duty Mountings: Heavy-duty clevis, pin-eye, or cross-tube mountings support repeated shock loads and demanding mining operations.
• Contamination-Resistant Sealing: High-pressure polyurethane seals and optional heavy-duty rod scrapers protect against dust, mud, and abrasive materials.
• Replaceable Bearings: Bronze or composite bushings simplify maintenance and extend component life.
• Optional Cushioning & Sensors: End-of-stroke cushioning reduces hydraulic shock; position sensors enable automated control and monitoring.
