Designatronics capitalized on its relationship with Kohara Gear and Quality Transmission Components became the exclusive North American distributor of the KHK product line.

The product line includes spur gears, helical gears, gear racks, spiral and sright tooth bevel gears, worm & worm gears, ratchets & pawls, gear couplings and splines. In 2000, Quality Transmission Components saw the opportunity to expand the product line. QTC added the Zetasassi line of belt and chain tensioners. Also added were neoprene timing belts, aluminum, steel and nylon timing pulleys, roller chain and planetary gearheads. QTC also became a distributor of Davall Stock Gear of England representing their inch gear line in the North American marketplace. All of these products are marketed under the Econobelt brand.
