For Powerful, Elaborate, and Swift Movements at the Forefront of Manufacturing

Precision reduction gears are key components of industrial robots used on automobile production lines. These gears make it possible to extract a tremendous amount of power from a small motor while at the same time allowing the industrial robots to make more precise movements. Without them,the robots would be unable to perform the powerful,swift, and precise actions needed to assemble the cars and other vehicles that we see all around us every day all over the world. Nabtesco has been a market leader in precision reduction gears for about 30 years now, and, as a specialist in the field, has consistently achieved technological innovation. Nabtesco’s precision reduction gears maintain high accuracy and rigidity as well as being compact and lightweight.They are therefore used not only in industrial robots but also in various other areas.
