About Forest City Gear

Forest City Gear manufactures custom fine- and medium-pitch gears in Roscoe, Illinois. Its capabilities cover gear hobbing, shaping and grinding, alongside machining operations used to prepare and finish gear blanks. The company describes work ranging from individual precision gears to production programs. Engineers can also use its Cut Teeth Only service when they already have gear blanks and need specialist tooth manufacturing. Inspection and engineering support address drawings, tooling and manufacturing requirements. The quote route provides a place to submit a gear drawing and discuss the required tooth form, finishing process and inspection scope.
