Common Pain Points of Excavator Hydraulic Cylinders

1. Cylinder Rod Bending or Damage, Affecting Work Efficiency

Pain Point: During high-intensity operations (e.g., breaking or heavy digging), the hydraulic cylinder rod may bend due to excessive external force, leading to downtime and costly repairs.
✅ Solution: Our cylinder rods are made with high-frequency surface hardening, achieving a hardness of up to 55, and treated with hard chromium plating to enhance bending resistance and durability, significantly extending their lifespan.

2. Cylinder Tube Wear, Leading to Leakage

Pain Point: The inner wall of the hydraulic cylinder tube may experience excessive wear due to high-pressure hydraulic flow and repeated piston movement, affecting sealing performance and causing hydraulic oil leakage.
✅ Solution: We use 25Mn alloy steel for the cylinder tube, which offers superior wear resistance compared to standard materials, ensuring long-term performance and reducing leakage risks.
