Common Pain Points of Excavator Hydraulic Cylinders and Our Solutions
1. Seal Deterioration, Causing Oil Leakage and Pressure Loss
Pain Point: Low-quality seals tend to harden and degrade under high-pressure and high-temperature conditions, leading to hydraulic oil leakage and reduced machine performance.
✅ Solution: We use imported Japan NOK & US SKF seals, ensuring long-lasting sealing performance with a hydraulic oil leakage rate below 1%, minimizing maintenance costs and maximizing efficiency.
2. Inconsistent Welding Quality, Affecting Cylinder Strength
Pain Point: Traditional manual welding can result in uneven weld seams, stress concentration, and potential cylinder failure, compromising operational safety.
✅ Solution: We employ automatic welding technology, ensuring smoother, more uniform welds that enhance structural strength and eliminate welding defects, making our cylinders more reliable.
3. Long Lead Times, Delaying Project Schedules
Pain Point: Some suppliers have long production cycles, leading to delays in equipment repairs or replacements, ultimately affecting construction schedules.
✅ Solution: We maintain ready stock for common excavator hydraulic cylinder models, enabling shipment within 7 days, reducing downtime, and keeping projects on track.
