Conventions
e Cup: The cup bore is a straight cone at the half angle a, widest at the cup's front face, where the wall is H/8 of the radial section H = (D - d)/2.
« Cone ribs and raceway: A back rib out to d1 over B/8; the raceway parallel to the cup bore, H/8 below d1/2 at the back rib; a front rib H/16 high over the last B/8.
« Corners: Back face corners are quarter-rounds of r1 (cone) and r3 (cup) at r_s min; the front corners and the rib joins are sharp. The shape isn't specified.
* No rollers or cage: Cone and cup are two separate solids that don't touch; the band between the raceways is empty. Rollers and cage are not modeled.
« Values: d, D, T, B and C at their nominals; d1 at SKF's approximate value (one source); a from the makers' axial load factor Y, a = arccot(Y / 0.4); rl and r3 at r_s min.
* Markings and grades: No markings. Tolerance class, clearance and lubricant are not geometry: one model per bearing.
