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

1. High intensity…Fatigue design adaptive cylinder designed according to loading frequency analysis are applied, and piston rod selection, processing technology, welding technology are inspected through ultrasonic fault detection. As it is HYDRAULIC SYSTEM usually designed for ruthless operation, it is showcased in high strength and high reliability.
2. Sealing system…seal bands of NOK from Japan and Parker from United states that may sure highly safety when work in aerial place. They are applied to prevent grit and dust, reduce oil leakage.
3. Cylinder body…the thickness of cylinder body and flange could be changed; the cylinder inner areas manufactured according to appropriate intensity and sizes have exceptional roughness and rigidity end better wearing 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 gradual stroke, counting balance end emergency close could be installed easily according to requirements. The concealed types can absorb the impact of buffer device by the end of stroke.

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