VR hydraulic cylinder is a kind of high pressure and durable cylinder. They are utilized in various hydraulic vibratory roller. which is ideal for non- cohesive soils, gravel, macadam, sand gravel blend and different concretes. it’s indispensable compaction apparatus for highway mine road ,dams, airports, harbors, sector ground and building foundation.
Hydraulic Cylinders 5
1. High intensity…Fatigue style adaptive cylinder designed according to loading frequency evaluation are applied, and piston rod selection, digesting technology, welding technology are inspected through ultrasonic fault detection. As it can be designed for high pressure operation, it is featured in high strength and high reliability.
2. Sealing system…seal bands of NOK from Japan and Parker from USA that may sure highly protection when function in aerial place. They are applied to prevent grit and dirt, 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 excellent roughness and rigidity end better putting on 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 features…valves with slow stroke, counting stability end emergency close could be installed easily according to requirements. The concealed types can absorb the impact of buffer device at the end of stroke.

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