  • How ball bearing is made

    Process There are four major parts to a standard ball bearing: the outer race the rolling balls the inner race and the cage. Races 1 Both races are made in almost the same way. Since they are both rings of steel the process starts with steel tubing of an appropriate size.

    A smaller ball interpolated exposes more of the surface to a faster moving cutter leading to a better finish. But the smaller cutter can flex more. Hence the need to balance these two factors. If you have a 4th axis or 5-axis mill you can try “Sturz” milling to combat the slow moving tip. See below for details.
