Aug 20 20201 Introduction Following current practices the effect of the operating temperature in the estimation of the fatigue life of the bearing is accounted for by means of a lubrication quality factor (κ) as defined in ISO 281 [] An increase of the running temperature of the bearing corresponds to a reduction of the lubricant viscosity hence a reduction of the lubrication quality which provides

Rolling

A rolling-element bearing also known as a rolling bearing is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two bearing rings called races The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding One of the earliest and best-known rolling-element bearings are sets of logs
