Abstract

Abstract The ecological balance in environment must be maintained despite growing industrial needs. Instead of controlling waste electrical and electronic equipment (WEEE), the hazardous substances were restricted at their origin and hence RoHS (Restriction of Hazardous Substances) directive came into picture. Connecting rod bearings are one of the important components of engine. It gives smooth rotation of connecting rod that connects the crankshaft and the piston. Lead is present in different amounts in bearing material because of its friction reducing property. However, due to negative health and environmental issues of lead, the use of lead is getting restricted in bearing. Thus, there is need to find out lead free bearing materials. This paper suggests different lead free alternatives to leaded bearing material.
