Abstract

These analyses of lubricants are to use various kinds of brand company’s fully synthetic lubricants available on the common market. There are three types of brand fully synthetic lubricants which are type A, B and C. To compare the quality of each brand lubricants, analyzing this type of lubricant brands, the method four ball tester machines to obtain the result. From this analysis, Four Ball Tester machine has been used to compare the quality of each lubricant brand. The balls used in four-ball tester was based on carbon-chromium steel ball bearings. The results obtained to present friction and wear characteristics are coefficient of friction (μ), and wear scar diameter (WSD). Each lubricant brand test was conducted for three different loads ( 150 N, 350 N, and 500 N), one different temperatures (80 ºC), and with constant speed (1000 rpm). The friction analysis also shows how the each lubricant prevents the ball bearing from wear, the less friction produces the highest quality of lubricant. Brand Type C is the best lubricant on friction because result applied load on Coeffiecient of Friction showed less friction compared to other brand. 2% extreme pressure additive selected as the best quantity of additive oil mixed in lubricant brand Type C because a good effect on change in the coefficient of friction result.
