The friction tests of variously heat-treated special cast steels against several kinds of plastics bearing materials were carried out, by the use of a friction testing machine in the absence of lubricant. 1) In regard to all the plastics bearing materials employed, with the fine structure of cast steel shaft material the sliding friction showed a lower coefficient of friction, and the coefficient of friction increased with a decrease in the hardness of cast steel shaft material. 2) With P.T.F.E. on all the tested cast steels, the sliding friction showed the lowest value, and the variations of frictional force with time were very small. 3) With nylon and phenolic plastics on cast steels, the coefficient of friction increased with decreasing load and sliding speed in the stable condition. The probable reason for this may be due to thermal properties of plastics and 'stick-slip' process.
