Abstracts: Submersible pump is mostly used in agriculture field for pumping purpose. Thrust bearing is very important part of submersible pump. In another word we can say that thrust bearing is the heart of the submersible pump. If thrust bearing is fail, then pump is useless. There are many reasons for failure of thrust bearing like misalignment, wear and tear, overloading, improper assembly, bearing metal selection, improper lubrication, poor surface finish of rotor, defects in manufacturing of bearing, high temperature, and friction. We give some remedies which prevent the failure of the thrust bearing due to given above reasons and increases the life cycle of thrust bearing, increase the pump efficiency and decrease the friction. We select bearing material such that it reduces the chance of overheating which is the main reason of the failure of thrust bearing. We take some step which prevents the misalignment between the thrust bearing and bushing in submersible pump.
