For instance, the causes of rib scoring, as one example of premature failure, may include insufficient lubrication, use of improper lubricant, faulty lubrication system, entry of foreign matter, bearing mounting error, excessive deflection of the shaft, or any combination of these. Rolling element bearings contain rolling elements in the shape of balls or cylinders. Yes. They are available as single-direction or double-direction bearings and the selection relies on whether the load is unidirectional or bidirectional. . Looks like youve clipped this slide to already. In each of these applications, ball bearings are used to support motor shafts as well as shafts of other rollers in the assembly. Do not expose them to any airborne contaminants, as even a tiny speck of dirt can cause premature failure. Bearings are classified under two main categories: Plain or slider bearing : - In which the rotating shaft has a sliding contact with the bearing which is held stationary . This prevents friction, heat generation and ultimately, the wear and tear of parts. In contrast to fatigue life, this premature failure is caused by improper mounting, handling, or lubrication, entry of foreign matter, or abnormal heat generation.

Bearing provides relative rotational freedom and transmits a load between two structures. Bearings bear the weight of the load and make things move without any or with much less friction. Follow The Lubrication Procedure Bearing life is greatly affected by how well the bearings are lubricated. Good luck. FUNCTION OF BEARING A bearing permits relative motion between two machine members while minimizing Frictional resistance. If they are heated above the permitted limit, they can permanently deform or soften the bearing steel, lowering load carrying capacity and resulting in a failure. PREPARATION FOR MOUNTING AND DIMOUNTING. Items that should be regularly checked during operation include bearing noise, vibration, temperature, and lubrication.
