FactoryRegistry lists 2,181 facilities whose primary industry classification is one of the 3 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced geared speed changers, industrial high-speed drives, gear motors, speed reducers, mechanical variable speed drives (gearboxes and allied products), in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.
