Hydraulics Drive- Hydraulic Cylinders

The loader using cylinder we produced is a piston and double acling type. Which can be used in the pole,bucket,moving arm, side switch of loader. They are matched for different tonnage loader according to clients requirements

This kind of durable high-pressure hydraulic cylinder is designed for large or intermediate excavator with max. pressure of 35MPa and operating temperature-20~100degree(for cold area: -40~90degree)
Features of the hydraulic cylinders:
This series products bear the following advantages:

A. Small size. light weight and highintensity, fatigue design, adaptive cylinder designed as per loading frequency analysis are applied, and piston rod selection, processing technology, welding technology are inspected through ultrasonic fault detection. As it is designed for high pressure operation, it is featured in small size, light weight, high intensity and high reliability.

Sealing system seal rings of Parker as well as special designed sealing system are applied to prevent grit and dust, reduce oil leakage and obtain optimal piston rod oil film.

Cylinder body the cylinder inner surfaces manufactured as per appropriate intensity and dimensions have excellent roughness and rigidity and batter wearing capacity after roll finishing.

Piston rod - high frequency quenching followed by nickel chrome plating to improve rust proofing and wear and scar resisting performance.

Safety/buffer functions - valves with slow stroke, counting balance and emergency Close can be installed easily according to requirements. The con-cealed ones can absorb the impact of buffer device at the and of stroke.
