A bottling plant in Brazil was using conventional deep groove ball bearings made of metal in various conveyor belts. The bearings had to be relubricated every two weeks and maintained at regular intervals. Corrosion on the shafts caused additional downtime.

To avoid this problem in the future, 60 igubal® spherical insert bearings were installed in the conveyor belts as a trial. The standard spherical insert bearings for metallic pillow block bearings and fixed flange bearings are injection moulded from our iglidur® J material. The spherical insert bearings are maintenance-free and corrosion-resistant and need no lubrication at all.
