Product introduction

Cylinder is the most important component of construction machinery. The traditional processing method is: broaching cylinder block - precision boring cylinder block - grinding cylinder block. The rolling method is: broaching cylinder block - precision boring cylinder block - rolling cylinder block, the process is three parts, but the time comparison: grinding cylinder block 1 m in 1-2 days, rolling cylinder block 1 m in 10-30 minutes. Contrast input: grinding machine or quilting machine (tens of thousands - millions), rolling knife (tens of thousands - tens of thousands). After rolling, the surface roughness of the hole decreases from Ra3.2-6.3um before rolling to Ra0.4-0.8-um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the cylinder increases by 25%. If only considering the influence of cylinder, the service life of cylinder can be increased by 2-3 times, and the efficiency of boring and rolling process can be increased by about 3 times than that of grinding process. The above data show that the rolling process is efficient and can greatly improve the surface quality of cylinder.

After rolling, there is no sharp edge on the surface of the cylinder, and the sealing ring or seals will not be damaged by long time moving friction, which is particularly important in the hydraulic industry.

We offer a large variety of excavator bucket cylinder assy for crawler tracked machinery for world famous and domestic famous crawler-tracked crane like hitachi, kobelco, sumitomo, zoomlien, sany etc.

Advantages

The thickness of Chromium plating is high to guarantee the long life of track adjuster piston. And we used imported high quality seal to guarantee the adjuster has good sealing property. What is more, the tube of track adjuster is made by forging. If the hydraulic pressure is too big. The tube will not be distorted.

Inspection

When assembling, we also need to test the sealing property by high pressure to see if there will be oil leakage or not.
