Conventions « Washers: Each washer T/3 thick: the housing washer from the back face at Z = 0, the shaft washer at the top, the middle third the gap between them.
« Web, no balls: A solid web ring joins the washers in the middle half of the band between D1 and d1, so the gap shows all round. Balls, cage and raceway grooves are not modeled.
e Corners: The eight washer corners are quarter-rounds of r_s min, the smallest the standard allows; the shape isn't specified. The web's edges are sharp.
« Values: d, D and T at their nominals; d1 and D1 at the makers' approximate values; r at r_s min, the only limit the sources give. « Markings and grades: No markings. Tolerance class and lubricant are not geometry: one model per bearing.
