Speaking of rollers, to a large extent, in terms of their cylindrical parts, first of all, we actually have to pay attention to its own use is actually divided into driving roller and driven roller; Furthermore, in terms of driving mode, it is actually divided into power roller and non-power roller, for power roller, it is actually divided into single chain roller and its double sprocket roller.

Next, for the non-powered roller, it is to a large extent will be divided into the inner tooth shaft roller and spring-loaded roller. Then, according to the structure of the form, in fact, it can be divided into cylindrical roller and cone roller.

Generally speaking, in terms of the roller itself, it actually is also adopted by the seamless steel tube is made and become, next, we also is to actually pay attention to according to the different process, then it will need to be adopted, such as aluminum alloy 6061 t5, then there is the 304 l / 316 l stainless steel, moreover, is also included 2205 duplex stainless steel and cast steel, alloy is solid forging steel reinforced for direct material.

Then, on the roller production is mainly including the initial roll, the initial static balance, then, it will include the shaft head interference assembly welding, there is a fine car and fine dynamic balance and other processes. If its form tolerance including roundness, cylindricity, and straightness are required to be below 0.2mm, we should pay attention to the fact that after finishing the machine, we need to go to the cylindrical grinder or roller grinder for grinding.

If there is any requirement on the surface hardness of roller workpiece, in view of this, we actually need to add a series of heat treatment procedures. Then, for the need of rust and corrosion prevention or wear resistance and support after roller forming, we should pay attention to the surface treatment or coating phenomenon.
