Hardened Thin Rings

Hardened thin rings like those outlined in this project, demonstrate the precision products we produce daily.

Throughout our years in business, we developed manufacturing strategies that allow us to produce precise thin gauge parts with unique dimensional tolerances. These hardened thin rings are made of bearing-grade alloy steel. Machining operations included CNC turning, internal grinding, and OD and centerless grinding to meet project specifications. Our heat treating process hardened the thin rings consistently without any compromise to the part’s dimensional integrity.

These rings featured dimensions of 4 1/2″ x 4″ x 1/4″ and within ± 0.0005″ tolerances. Precise 8 and 16 micro finishes were also used. To learn more about this project, contact us today.
