Roller is a cylindrical part, divided into drive and driven roller. It will be widely used in the rotary screen printing machine and its digital printer, and then in the mine conveying equipment and its paper making and packaging machinery and other different kinds of transmission and conveying system. For the roller, it is made of seamless steel pipe. At the same time, different processes and materials will be used according to different processes.

Then, we also is to pay attention to, actually just split type and couplet body type magnetic roller differ, in terms of its separation design, it has pointed out its pillow in the shoulder is a sealed type, in the heat treatment to the 60 to 62 rockwell hardness, to a large extent, actually is also can directly to ensure that pillow shoulder itself wear-resisting performance, and to change the pillow shoulder after a few years can remove, as far as possible in the back and not waste the original order of the flexible blade.

Regarding its couplet body design, it is referring to the pillow shoulder and roll material as an organic whole, advantages of speaking, its production cost will be cheaper, made a relatively short time, however, in terms of its shortcomings, can't pillow with poor shoulder hardness and wear resistance, at that time, namely can lead to the relatively short the whole life of roller.

In addition, we are also to pay attention to the maintenance of the roller, in order to extend the service life of the roller itself, it is to a large extent is to pay attention to the corresponding roller maintenance work.

After, on the roller maintenance, point to say, that is to pay attention to should be to regularly clean up the roller dust and other foreign bodies. Then, we are actually to pay attention to the regular inspection of the roller shell and end cover welding place is not firm, on its lubrication performance is better, to pay attention to reduce the loss of wear. Avoid overload and extend the service life of the roller.
