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.
