xiros lubricant-free conveyor rollers

Under the brand name xiros, igus has developed maintenance-free, lubricant-free polymer ball bearings. For the food and packaging industry, this reduces the risk of contamination. The range includes a ready harnessed system solution consisting of a blue PVC tube as well as two flange ball bearings made of xirodur B180 with stainless steel balls. All components used in these new guide rollers are FDA compliant. The solution comes in two installation sizes with outer diameters of 50 and 63 mm, and lengths of 100 to 1000 mm.

Compared to stainless steel tubes, the food-grade plastic tube weighs only about one-third as much, which in turn has an effect on the required drive energy when the rollers themselves are moved, eg, in film storage. Also, the dry-operating xiros polymer ball bearings achieve less friction than lubricated ball bearings made of metal, since the balls do not have to overcome the resistance of the lubricant.
