Forest City Gear

Forest City Gear, a precision gear manufacturer based in Roscoe, Illinois, specializes in fine- and medium-pitch custom gears for critical applications in aerospace, defense, robotics, medical instrumentation, and other high-reliability sectors. The company operates two facilities: its primary gear cutting and inspection plant and a dedicated turning facility known as Roscoe Works. The company’s manufacturing capabilities include the production of spur and helical gears, involute splines, worms, worm gears, sprockets, and other cylindrical gear types. These components are produced in a wide range of materials and geometries, including small-scale parts held to tight tolerances for use in environments with extreme thermal, mechanical, or vacuum conditions. Their gears have been deployed in terrestrial and aerospace systems, including the International Space Station and various NASA rover platforms. Forest City Gear supports both complete part manufacturing and contract gear cutting. Under its “Make Complete” workflow, parts are manufactured from raw stock through final inspection, including material sourcing, turning, heat treatment coordination, and finish grinding. Design-for-manufacturability input is offered at the early stages of project development. The “Cut Teeth Only” workflow applies to customer-supplied blanks and includes gear cutting, measurement, and final inspection. The company maintains a tooling inventory of over 7,000 hobs and 5,000 shaper cutters, enabling short lead times on a wide range of standard and custom profiles. Forest City Gear holds ITAR registration and maintains certifications to AS9100D / ISO 9001:2015 and ISO 13485:2016, with Nadcap accreditation for magnetic particle inspection (MPI). The company is an active member of the American Gear Manufacturers Association (AGMA). Representatives will be available at Booth 419 to provide technical information on current capabilities, tolerances, materials, and lead time estimates.
