  • Radial, Angular, and 4-point Contact

    2018-8-27 · A bearing is considered a thin section when the bore diameter is greater than four times the radial cross section. Within any thin section ball bearing series, the cross section remains constant as the bore diameter changes. Typically the cross section is twice the ball diameter, and nominal dimensions are given in inches.
