    Oct 24, 2017· The signs of overheating include discoloration of the cages, balls, and rings, which turn from gold to bluish. Exposure to temperatures that exceed 400ºF anneals the ball and ring materials. This process leads to a loss in hardness and a reduction in the bearing capacity. If left unresolved, early failure may occur.

  • Vibrating Screen Working Principle

    IntroductionNamingMechanismApplicationsPurposeCauseUseSpecificationsSafetyOperationAssessmentCriticismsAnalysisExampleAdvantagesConstructionTypesDesignThe main cause of mechanical failure in screen decks is the vibration. Even the frame, body and bearings are affected by this. The larger the screen the bigger the effect. The vibration will crystallize the molecular structure of the metal causing what is known as METAL FATIGUE to develop. The first sign that an operator has indicating that the fatigue in the body of the screen deck is almost at a critical stage in its development are the hairline cracks that will appear around the vibrations point of origin. The bearings
