Company Profile

Guangzhou Guoli Engineering Machinery Co., Ltd., located in Guangzhou, China, is a specialized manufacturer of excavator hydraulic cylinders, including boom cylinders, arm cylinders, and bucket cylinders.

We operate our own production facility, equipped with advanced CNC machinery and staffed by highly skilled, experienced technicians. This allows us to maintain strict control over quality and ensure that every cylinder we deliver is reliable, durable, and ready for demanding job site conditions.

Our cylinders are known for their consistent quality, reasonable pricing, and prompt delivery. Over the years, we have successfully exported to North America, South America, Southeast Asia, the Middle East, Europe, and Africa, earning the trust and recognition of clients worldwide.

Whether you're sourcing for replacement parts or custom-built solutions, Guoli is your trusted partner in hydraulic cylinder manufacturing.

Our hydraulic cylinders are built with performance and durability in mind:

Piston Rod: Fully tempered and surface-hardened via high-frequency quenching, reaching a hardness of HRC55 for superior wear resistance.

Forged Components: Rod heads, cylinder ends, and caps are forged to match OEM-grade materials, ensuring strength and precision.

Welding Technology: All joints are completed using automatic welding, delivering smoother seams and stronger bonds than manual methods.

Cylinder Tube: Made from high-strength 25Mn steel—the same as OEM cylinders—each tube is sandblasted and treated with a two-layer baked paint finish (primer + topcoat) for enhanced corrosion resistance.

Sealing System: We use premium NOK and SKF seals to ensure excellent sealing performance and long-term pressure retention.

Precision Assembly: Our cylinders are assembled using automated assembly machines, minimizing the risk of loose components such as nuts or fittings.

Pressure Testing: Each unit undergoes rigorous hydraulic pressure testing before shipment to prevent any leakage issues.
