  • Preloading of Bearings - Bright Hub Engineering

    2008-11-29 · This article describes what is preloading, preloading of bearings, need for preloading of bearings. Bearings apart from being mounted on the shafts and housings have to be preloaded properly for their proper functioning. Preloading is the methodology by which we remove the internal clearance in the bearing by applying a permanent thrust load to it.

    Bearing rings and balls are not perfectly round and the balls and raceways, even after extensive fine grinding and polishing, are not perfectly smooth. There are machining imperfections in the form of rough or uneven surfaces which will cause one ring to move or oscillate radially in relation to the other causing bearing vibration and noise.
