In general the roller GB is composed of 5 parts, because some small parts of roller can be ignored without, so some manufacturers to save costs in small parts manufacturers move the hands and feet, hope customers buy to understand clearly. Here I come to introduce the composition and structure of roller:

1 axis: with high precision roller shaft made using processing machinery.

2: the selection of senior special pipe pipe with high precision to ensure uniform rotation operation process of roller.

3 bearing: according to the company many years of experience, the best fit tolerance selection between the bearing and the bearing seat and the shaft. Considering that tolerance of bearing itself and its adaptation to the operation China temperature rise conditions, deep groove ball bearings are our use of group C3, ZZ double seal clearance.

The 4 bearing seat by a bearing: deep drawing materials and precision metal mold processing base adopts automatic welding and welding method in the pipe ends. The overall structure of the resulting strength uniform, ensure operation process between steel tube and bearing seat firmly link. Even in the running process by the impact of high-speed conveyer belt, it will not be damaged phenomenon.

The labyrinth seal: 5 unique lacunar type oil we seal belonging to the non contact type structure, the rotation resistance and longer its reasonable structure so that it has a smaller service life. Bulk material conveyer is particularly suitable for long distance, large conveying capacity. After testing the authority of the state institutions and the Japanese NC company confirmed, dustproof and waterproof performance of the seal is much higher than the national standard, and higher than that of the Japanese JIS standard, has obtained the national patent. Its use effect is very satisfactory.
