Vibrating screens, also known as shaker screens, subject bearings to extremeoperating conditions. High g forces due «g» to constant acceleration and impact from material on the bed require bearings with extra capacity and robust cages. The high loads cause deflection of the shafts and housings so the bearings must accommodate misalignment in operation. Lastly, the application subjects the bearings to high speeds and highly contaminated environments so the bearings must operate smoothly and have minimalfriction.
These bearings can be used in mining, construction, aggregate, asphalt recycling, steel manufacturing, and general industrial equipment where heavy loads, vibration, and impact loads are common. Typical example sinclude vibrating screens and crushers.
