(19) Part of the finished cap inspection department where cups are micrometrically gaged to a tolerance of .001 of an inch. (20) Part of the assembling department where parts which have passed the series of rigid inspections are finally assembledinto complete bearings. (21)One of the stamping operations in the construction of the one-piece annealed cage or rollretainer. (22) Closing-in machine where the roll retainer or the cage of Timken bearings is formed to keep the roll in direct alignment. After the case hardening process is finished, the partsare ground to finished size. The cups are ground on in-ternal cup grinders and the rolls on the same make ofgrinder supplied with automatic feed. The toleranceson the grinding operations are .001 of an inch on thecups and .0005 of an inch on the rolls. One of the most interesting machines in the entireprocess of manufacture is the automatic taper gaugingmachine where the rolls are gauged electrically. All ofthe rolls not of the exact taper
