A Deister Vibration Technician was sent onsite to evaluate the situation in detail. Upon inspection, the vibrating screen showed no obvious or visual signs of conditions such as bottoming, impacting or broken springs, for example. A field vibration study was started to help diagnose any issues.

Vibrating screen gearbox bearing failure due to flaking of the inner raceway. ISO 15243:2004 - 5.1.2 subsurface initiated fatigue due to overloading (Axial shock load).

Bearings in vibrating screen applications are subject to impact loads and rotating loads – special fits are required to prevent inner and outer ring creep. Shaft diameter and housing bore diameter tolerances are given below for two-bearing screens, double- and triple-shaft screens, and the eccentric bearings in four-bearing screens.
