Abstract: Cotton seed oils have traditionally been applied in some uses but recent trends suggest their economic usefulness as industrial fluids. Increasing crude oil prices and emphasis on the development of renewable, environmentally friendly fluids have brought cotton seed oils to a place of importance. As environment pollution and health problem became more and more seriously concerned, the use of environmentally friendly lubricants is strongly supported by political parties, regional and local governments. The objective of this work is to determine the tribological properties of cotton seed oil & to determine the influence of lubricant on wear and pressure by using four ball tester machine. Further an attempt has been made to identify the influence of cottonseed oil in reducing the wear & chemical transformation. The performance of cottonseed oil is also being compared with commercial hydraulic oil.
