Our special pillow block bearings were used for the conveyor rollers in the sludge treatment plant.
Originally, there was a consideration to extend the lifespan because the previously used pillow block bearings were worn out by sludge. To prevent sludge from remaining in the sliding area, we made special holes along the outer diameter of the bushing to the inner diameter and milled spirals into the inner diameter. These holes serve to allow the sludge that accumulates in the inner diameter to flow through and help extend the lifespan by enabling a water solution.
In fact, tests with this specification showed that wear was significantly reduced compared to before. As a result, the replacement intervals were extended from a few months to years, leading to a reduction in maintenance effort.
