Hydraulic Cylinder for Loader & Excavator (HRLE Series)

HRLE Series Hydraulic Cylinder for Loader & Excavator

Summary
This kind of durable high-pressure cylinder is designed for large or intermediate excavator with max. Pressure of 35MPa and operating temperature -20degree~100degree(for code area: -40degree~90degree
Features

This series cylinders has the following advantages:
1. Small size, and high intensity^ Intensity, 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.
2. Sealing system^ seal rings of Parker as well as special designed sealing system are applied to prevent grit and dust, reduce oil leakage.

3. Cylinder body^ the thickness of cylinder body and flange can be changed; The cylinder inner surface manufactured as per appropriate intensity and dimensions have excellent roughness and rigidity and better wearing capacity after roll finishing.
4. Piston rod^ high frequency quenching followed by hard chrome plating to improve rust proofing and wear and scar resisting performance.
5. Safety/buffer functions^ valves with slow stroke, counting balance and emergency close can be installed easily according to requirements. The concealed ones can absorb the impact of buffer device at the end of stroke.
