Recently, automobile engine is required smaller size and low fuel consumption for restraining global warming. These contributes into move frictions in harsh conditions for the plane bearings. Tribological characteristics such as wear resistance and seizure resistance are required for plane bearings. For this reason, resin overlay bearings are used in automobiles. However, due to the thermoplasticity of PAI, it is concerned that the mechanical properties may change under high temperature. In this study, we investigate the influence of heating temperature on the surface strength of resin overlay by performing reciprocating tribotests and SAICAS tests. In reciprocating tribotests, the wear resistance was improved by subjecting the test specimen to heat treatment. Also, the friction force increased in the area where the resin overlay was delaminated. In SAICAS tests, the shear strength of resin overlay decreased as the test temperature increased.
