HYDRAULIC CYLINDER FOR VIBRATORY ROLLER
VR hydraulic cylinder is a type of high pressure and durable cylinder. They are used in various hydraulic vibratory roller. which is ideal for non- cohesive soils, gravel, macadam, sand gravel blend and various concretes. it's indispensable compaction apparatus for highway mine road ,dams, airports, harbors, sector ground and building base.
特点
1. High intensity...Fatigue design adaptive cylinder designed as per loading frequency evaluation are applied, and piston rod selection, digesting technology, welding HYDRAULIC CYLINDER technology are inspected through ultrasonic fault detection. Since it is usually designed for high pressure operation, it is showcased in high strength and high reliability.
2. Sealing system...seal bands of NOK from Japan and Parker from USA that can sure highly basic safety when work in aerial place. They are put on prevent grit and dust, reduce oil leakage.
3. Cylinder body...the thickness of cylinder body and flange can be changed; the cylinder inner areas manufactured as per appropriate intensity and dimensions have excellent roughness and rigidity end better wearing capacity after roll completing. They have 100% non-destructive test.
4. Piston rod...high frequency quenching accompanied by hard chrome plating to improve rust proofing and wear and scar resisting performance.
5. Safety/buffer features...valves with slower stroke, counting stability end emergency close can be installed easily according to requirements. The concealed ones 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 the latest models of of vibratory roller. They period used for changing direction. We can style and make different specifications 
steering cylinder according to clients' requirements
