VR hydraulic cylinder is a type of high pressure and heavy duty cylinder. They are used in various hydraulic vibratory roller. which is ideal for non- cohesive soils, gravel, macadam, sand gravel combination and various concretes. it’s indispensable compaction products for highway mine street ,dams, airports, harbors, sector ground and building foundation.

1. High intensity…Fatigue style adaptive cylinder designed according to loading frequency evaluation are applied, and piston rod selection, processing technology, welding technology are inspected through ultrasonic fault detection. As it is certainly designed for ruthless operation, it is featured in high intensity and high reliability.
2. Sealing system…seal bands of NOK from Japan and Parker from United states that can sure highly protection when function in aerial place. They are put on prevent grit and dirt, HYDRAULIC SYSTEM reduce oil leakage.
3. Cylinder body…the thickness of cylinder body and flange can be changed; the cylinder inner surfaces manufactured according to appropriate intensity and measurements have exceptional roughness and rigidity end better putting on capacity after roll finishing. They have 100% non-destructive test.
4. Piston rod…high frequency quenching followed by hard chrome plating to improve rust proofing and wear and scar resisting performance.
5. Safety/buffer features…valves with slower stroke, counting balance end emergency close can be installed easily according to requirements. The concealed ones can absorb the impact of buffer device at the end of stroke.

Vibratory roller hydraulic cylinder we produces is a piston style cylinder, it could be matched for different models of vibratory roller. They period used for changing path. We can style and make different specs steering cylinder according to clients’ requirements
