Sumitomo Drive Technologies has been trusted for over 130 years to provide quality products and innovative solutions to help our customers solve their complex challenges. This rich history has made us a leading United States manufacturer of gear drives, speed reducers, inverters, and control products in a wide variety of applications for leading global brands. 

The strength of our Cyclo Technology backs our top gearboxes and speed reducers. Due to the cycloidal disc design, the reduction components run in a smooth, rolling motion to prevent tooth breakage typical in conventional gearing. The result is a durable solution with a renowned, long-lasting gear drive with minimal vibration, 500% momentary shock-load capacity, low backlash, and extended operational life.

Whatever gear drive you're looking for--Sumitomo has it, whether it's inline/concentric products like our Cyclo gearmotor, right-angle gearbox options, including our Bevel BuddyBox 4, or parallel-shaft gearboxes like our Helical BuddyBox. If you need power that packs a punch--our large industrial gearboxes that include our Paramax and Hansen lines are a great fit. 

Brands count on our industrial gearboxes and speed reducers in every industry, from Food & Beverage to Mining to Parcel Handling. Gearbox support from Sumitomo doesn't end after installation. Our experienced Gearbox Repair & Restoration specialists are always available to handle repair, gearbox maintenance, retrofitting, rebuilding, and anything else you need for your operation.
