The higher the operating amplitude of vibrating equipment, the shorter the service life of the equipment's bearings. Bearing service life will be satisfactory even if all the available eccentric mass that was originally provided with the equipment is used.
Vibrating screen equipment in mineral processing has a tough job. The eccentric motion with high vibration coupled with heavy loads puts a strain on components, and especially bearings that are exposed to the elements and abrasive dust. It's an environment where equipment failure is often accepted as a cost of doing business.
