Benefits of Vibrating Screen Bearings

Twice the service life of conventional bearings

Reduced maintenance costs

High dynamic and static load ratings – 1.25 times higher load ratings

Vibration damping and high resistance to heavy or shock loads

High speed performance and low operating temperature rise

Better roller guidance and smooth running – less bearing damage due to sliding, surface fatigue, spalling

Vibrating screens, also known as vibrating screens, subject bearings to extreme operating conditions. The high g forces due to the “g” constant acceleration and the impact of the material on the bed require bearings with extra capacity and strong cages. The high loads cause deformation of the shaft and housing, so the bearings have to be adapted to the misalignment in operation. Finally, the application exposes the bearings to high speeds and highly contaminated environments, so the bearings must run smoothly and with minimal friction.
These bearings are used in mining, construction, aggregates, asphalt recycling, steel manufacturing and general industrial equipment where heavy loads, vibrations and shock loads are common. Typical examples include vibrating screens and crushers.
