Heat Resistant 50kg/M Heavy Duty Conveyor Rollers With Vacuum Sealed
Heavy Duty Conveyor Steel Industrial Roller in Hot Sale
In a variety of polluted environments, the roller that can keep rotating flexibly is a good roller; the belt conveyor roller has the characteristics of corrosion resistance and wear resistance, and the effect is more ideal. Because the dust in the coking plant is fine and permeable, it is very easy to contaminate the roller bearing; the sharp hard particles of coke also cause serious wear on the roller tube wall. Therefore, the steel pipe roller will be worn through the pipe wall in two to three months in the coking plant. Although both ceramic rollers and cast stone rollers have good wear resistance, due to poor manufacturing accuracy and sealing performance, the bearings in the rollers will be contaminated in three or four months, and they will make a harsh sound during operation. Was stuck quickly. Belt conveyor idler ultra-high molecular weight polyethylene (nylon) idler and glass fiber reinforced plastic composite idler, the same accuracy and sealing performance cannot be guaranteed, the bearing is damaged in three or four months, and the pipe wall is worn through.
