The base material for sintered parts such as sliding bearings or other formed parts are iron, bronze, iron with bronze and other metal in powder form. This powder is formed under high pressure in dies into a temperature which is just below the melting point. According to the work condition, the bearings can impregnated different oil or solid lubricants for the self-lubricating.
    Sintered self-lubricating bearings are the ideal and economical solution for applications where lubrication is difficult or can not be given.
