The Effect of Lubrication on Tribological Properties of Bearing Materials Using Pin on Disc: A Review

Abstract

A bearing is interposed between two surfaces in relative motion to minimize the friction. In generally used bearing materials like steels or its alloys depends on the continuous presence of a very thin -millionths of an inch-film of lubricant. Due to restricted lubricant flow or long run increase excessive temperature etc. These are the several reasons of failure of the bearing and this rate of failure of the bearing can be avoided by proper selection of bearing materials and lubricating system. The materials are processed to achieve desirable properties to maximize bearing performance and life. Wet condition lubricants are oils, which produce an oil film between two mating parts i.e. reduce wear and friction. Dry lubricants are materials which, despite being in a solid phase are able to reduce friction between two surfaces against each other without need a liquid oil medium. Over the years, the author has evaluated an P1n-on-d1sk tribometer will be described and discussed as will experimental methods for evaluating Wet conditions and Dry conditions. When evaluating what solid lubrication and hydrodynamic lubrication should be used for a specific application, the only sure way to determine how well it will perform.
