Harmonic Drive Technologies is one of the world's leading manufacturers of precision gear systems, gearboxes, servo actuators and custom assemblies based on the unique principle of harmonic drive. We are also an importer of heavy-duty precision gear and servo actuation systems based on the cycloidal gear system known as the RV drive.

Main Industries served:
semiconductor, factory automation, medical diagnostic equipment, printing and converting and aerospace.

A focus on complete solutions
Harmonic Drive Technologies is more than a provider of gearing, actuators and other products. We are a solution provider. Our complete solutions to precision motor control problems include: integrated motors and electronics; custom assemblies for machine manufacturers; and material and design solutions for aerospace and other problematic manufacturing environments. We also offer applications support, prototyping, relatively fast delivery, and field sales support.

Lighter, smaller, stronger
Harmonic Drive Technologies offers products with powerful precision in small packages. Our aim is to give machine manufacturers the muscle and precision needed to maneuver machine elements without occupying any more space than necessary.

A subsidiary of Teijin Seiki
Teijin Seiki Co., Ltd. of Tokyo, Japan, a company that produces the complimentary industrial robot drive technology called the RV gear, acquired Harmonic Drive Technologies in 1991.
