Lead (Pb) bronze material is used for the manufacturing of bearings. Lead provides less friction and wear-related properties to bronze. During working of the bearings the lead contained micro-chips mixes with the lubricant oil and makes its disposal difficult. Rotational speed and applied load are the two main parameters on which the working and amount of wear from the bearing depend. So it is important to find out an optimum set of speed and pressure on which a particular bearing should operate to minimize the wear and hence minimize the lead-contaminated lubricating oil. In the present work, Taguchi technique has been used to find out the optimum values of speed and pressure. To measure the specific wear rate (SWR) and coefficient of friction (COF) of the leaded bronze material, it is made to slide on a mild steel material and amount of wear and coefficient of friction has been recorded using a pin on disc machine using ASTM-G99 standards.
