drylin® R RJUM-01 bearings were used in a self-cleaning filter that was designed for the use in areas that are endangered for explosions. It positions and stabilizes a shaft with a stripper that cleans a filter plate. The bearing position was determined by the geometry of the system, and its vertical orientation. drylin® R guarantees perfect density, which is essential for an application in a dangerous environment. There are additional pluses like being lubrication- and maintenance-free, having a low friction coefficient, being UV resistance, and being resistant to chemicals.
