Heavy-Duty Hydraulic Cylinders for Mining & Construction Equipment

Yile Machinery is a specialist manufacturer of high-performance, heavy-duty hydraulic cylinders engineered to operate in the world's most demanding environments. Our cylinders are the powerhouse behind mining excavators, loaders, and other large-scale machinery, providing the force and reliability needed for maximum productivity.

This mining excavator cylinder is a testament to our engineering and manufacturing excellence, built to withstand extreme shock loads and continuous operation.

Built for the Toughest Environments: Mining-Grade Reliability

Hydraulic cylinders on mining and construction equipment face a unique set of challenges, from abrasive dust and debris to immense impact forces. We design and build our cylinders specifically to overcome these conditions:

• Robust Construction: We use high-strength steel and robust welded construction to ensure maximum structural integrity.

• Superior Sealing: We utilize premium, high-pressure sealing systems from world-class brands (e.g., Parker, Hallite, SKF) to prevent leaks and protect internal components from contamination.

• Contamination Resistance: Hard chrome plating on the piston rod and precision honing of the cylinder barrel provide an ultra-smooth, durable surface that resists scoring and extends seal life.

Core Components of Our High-Performance Cylinders

Every component is selected and manufactured for maximum service life.

• Cylinder Barrel: Made from high-strength seamless steel tubing, honed to a mirror finish for optimal seal performance.

• Piston Rod: Precision-ground, induction-hardened steel, plated with a thick layer of hard chrome for exceptional wear and corrosion resistance.

• Piston & Gland: Machined from high-strength ductile iron or steel to handle extreme pressures without deformation.

• Integrated Cushioning: Optional cushioning at the end of the stroke reduces impact, minimizing stress on the machine's frame and improving operator comfort.

Custom Manufacturing for All Excavator Functions

We manufacture and supply custom cylinders for all primary excavator functions, built to OEM specifications or your unique requirements.

• Boom Cylinders: The largest and most powerful cylinders, responsible for lifting the entire boom assembly.

• Arm (Stick) Cylinders: Provide the force for extending and retracting the excavator's arm.

• Bucket Cylinders: Control the curling and dumping motion of the bucket with high speed and force.

We can produce cylinders as direct replacements for major brands like Bucyrus,Liebherr,ЭКГ,ЭШ,and more, or manufacture fully custom designs from your technical drawings.
