Superior Gearbox Direct is an aftermarket web site hosted by Superior Gearbox Company. Superior Gearbox Company has been producing gear drives for Original Equipment Manufacturers since 1975. Superior Gearbox Direct offers common replacement parts such as seals, seal repair kits and bearings. We are also offering standard bevel gear drives and some machine specific gear drives. Machine specific gear drives were produced for the Original Equipment for many years and were discontinued. These are the original parts purchased by the Original Equipment Manufacturer not imported copies. If you have a Superior Gearbox that was removed from a piece of machinery that is not listed on this site, please contact the Original Equipment Manufacturer or your current dealer for that brand of machinery. Distributors and Retailers please contact your Superior Gearbox Company customer service representative with your Federal Tax I.D. number to be set up as a Superior Gearbox Company Reseller. We hope you find the site convenient and easy to use.
