Roller: roller has a light weight, easy to manufacture, low cost, small roller rotation resistance made, can effectively reduce the power consumption of the conveyor. Roller aging resistant lithium grease, not only play a good lubrication UHMWPE roller processing, but also can be used with seals, enhance sealing effect. Roller Type Standard: Roller classified according to their use of self-aligning roller, buffer roller, roller trough, parallel to the roller. The role of self-aligning roller conveyor is to correct the deviation of ultra high molecular weight polyethylene roller, usually conveying installation Rotary trough aligning roller ultra high molecular weight polyethylene roller price segment overloaded machine, empty install a parallel aligning roller upload section. Buffer roller is applied to the tail rack of the actual situation, when the subject material, can reduce material impact on the belt, help along the long life of the belt.
