HYDRAULIC CYLINDER FOR VIBRATORY ROLLER
VR hydraulic cylinder is a kind of high pressure and durable cylinder. They are used in various hydraulic vibratory roller. which is suitable for non- cohesive soils, gravel, macadam, sand gravel combination and various concretes. it’s indispensable compaction products for highway mine road ,dams, airports, harbors, sector ground and building base.
Features
1. High intensity…Fatigue design adaptive cylinder designed as per loading frequency evaluation are applied, and piston rod selection, processing technology, welding technology are inspected through ultrasonic fault detection. As it is usually designed for ruthless operation, it is featured in high intensity and high reliability.
2. Sealing system…seal rings of NOK from Japan and Parker from USA that may sure highly basic safety when function in 
aerial place. They are put on 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 dimensions have superb roughness and rigidity end better putting on capacity after roll completing. They have 100% non-destructive test.
4. Piston rod…high frequency quenching accompanied by hard chrome plating to boost rust proofing and wear and scar HYDRAULIC CYLINDER resisting performance.
5. Safety/buffer functions…valves with slower 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 creates is a piston design cylinder, it can be matched for different models of vibratory roller. They period used for changing direction. We can style and make different specs steering cylinder according to clients’ requirements
