VR hydraulic cylinder is a kind of high pressure and heavy duty cylinder. They are utilized in HYDRAULIC SYSTEM different hydraulic vibratory roller. which is suitable for non- cohesive soils, gravel, macadam, sand gravel blend and different concretes. it’s indispensable compaction gear for highway mine street ,dams, airports, harbors, sector ground and building base.

1. High intensity…Fatigue design 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 high pressure operation, it is featured in high strength and high reliability.
2. Sealing system…seal rings of NOK from Japan and Parker from United states that can sure highly protection when work in aerial place. They are put on prevent grit and dirt, reduce oil leakage.
3. Cylinder body…the thickness of cylinder body and flange could be changed; the cylinder inner surfaces manufactured according to appropriate intensity and dimensions have exceptional roughness and rigidity end better wearing capacity after roll finishing. They have 100% nondestructive test.
4. Piston rod…high frequency quenching followed by hard chrome plating to boost rust proofing and wear and scar resisting performance.
5. Safety/buffer functions…valves with slow stroke, counting balance end emergency close can be installed easily according to requirements. The concealed types can absorb the influence of buffer device at the end of stroke.

Vibratory roller hydraulic cylinder we generates is a piston design cylinder, it can be matched for different models of vibratory roller. They period used for changing direction. We can design and make different specifications steering cylinder in accordance to customers’ requirements
