Abstract: The main objective of this research was to investigate the performance of refined, bleached and deodorized (RBD) palm olein by using a pin-on-disk tester. The pin was held to the rotating plain disk at a normal load (10N) according to the American Society for Testing and Materials (ASTM) G99. The RBD palm olein was used as the main lubricant owing to a greater awareness of the greenhouse effect phenomenon which has lessened the usage of conventional lubricants that affect our environment. This trend has strongly encouraged the government to use eco-friendly and biodegradable lubricants in the manufacturing industry. RBD palm olein was selected due to its superior tribological properties and large production in Malaysia. The tests were carried out using a direct lubricant flow of RBD palm olein and hydraulic oil on a plain disk at two different speeds (0.4 m/s and 4 m/s). The material used for both frictional surfaces was stainless steel. The results clearly show that the wear obtained when using the RBD palm olein was lower than that of the hydraulic oil. In addition, the coefficient of friction and wear scar diameter of the sample lubricated with RBD palm olein was remarkably lower at low speeds, and approximately the same as hydraulic oil at high speeds.
