GLPARTS Excavator Hydraulic Cylinders – Engineered for Precision, Built for Performance

GLPARTS hydraulic cylinders are purpose-designed for the demanding conditions of excavator operations, offering broad compatibility across a wide range of digging and lifting applications. Every cylinder is manufactured in China under strict compliance with the ISO 9001:2015 quality management system and dedicated excavator cylinder production standards—ensuring 100% reliable performance, efficiency, and stability on the job site.

Our piston rods undergo a multi-stage precision manufacturing process to deliver unmatched durability:

Premium Material Selection: We use high strength alloy steel, carefully selected for its superior load-bearing capacity and resistance to fatigue, ensuring long-lasting performance in demanding excavator applications.
Ultra Precision Machining: Advanced machining processes maintain diameter tolerances within microns, delivering a perfect fit and smooth operation for maximum efficiency.
Specialized Surface Hardening: Induction hardening combined with hard chrome plating forms a dense, uniform wear-resistant layer with hardness above HRC55, providing exceptional protection against impact, abrasion, and abrasive materials like sand or gravel.
Precision Polishing: Each piston rod is polished to achieve a straightness deviation of ≤0.1 mm/m, reducing hydraulic resistance and enabling faster, more responsive cylinder performance.

By combining precision engineering, rigorous quality control, and advanced surface treatments, we delivers hydraulic cylinders that stand up to the toughest excavator workloads - day after day.

Packing

Each hydraulic cylinder is securely packed in a custom-made solid wood crate with a panel thickness of ≥15 mm. Inside, moisture-resistant boards and EVA cushioning pads are added to prevent movement and absorb shocks, ensuring the cylinder remains stable and protected throughout transit.
