Note (General): This paper describes three topics for the study on oil-lubricated ball bearings and a space lubricant. Firstly, in-situ measurement of oil film thickness during bearing operation was achieved by LIF method. The film thickness on the raceway was decreased by continuous ball passing, and, finally, very thin film of just 0.1 - 0.2 micrometer contributed to bearing lubrication. Secondly, a clouding phenomenon of MAC oil by UV and low-temperature exposure was investigated. Combination of antioxidants and extreme-pressure additives affected the color stability of MAC. Lastly, studied was the influence of oil-wettability on bearing performance using contact electric resistance method. It was confirmed that the dewetted bearing could form sufficient EHL film and operate under hydrodynamic lubrication.
