  • Precision of bearing race is very important to maintain the clearance between ball and inner race. In internal grinding of bearing race, its roundness is dependent on shoe wear, accuracy of jig, dressing method and grinding conditions. In this study, the characteristics of shoe wear and eccentricity of workpiece were investigated experimentally. When wear of fornt shoe wear reaches at 100.mu. m and that of rear shoe reaches at 114 .mu. m, eccentricity of inner race is increased to 1.4 .mu. m. Roundness of race is mainly related to wear of rear shoe and ring type shoe is recommended to improve roundness of race.
