Green technology policies and other environmental legislations have driven researchers to channel their attention into bio-based lubricants. In the current study, the performance of the bio-based lubricant, palm mid olein (PMO), in journal bearing applications was examined. A comprehensive journal bearing test rig was used to evaluate the tribological behaviour of PMO and to compare it with a mineral-based oil (SAE 40). A bearing, with a length to diameter ratio of 0.5, was used in accordance with variations in the journal speed and radial load. It was found that PMO presented a higher maximum pressure and better thermal resistivity compared to SAE 40. PMO also demonstrated a lower friction coefficient in all testing conditions.
