About Us
Flex Harmonic Since 1968
Flex Harmonic has been at the forefront of the precision harmonic gearing and motion control industry, and a key player in robotic components since 1968, when we were then named Conic Systems.
Our customers benefit from the "USA Made Advantage," with our harmonic drives manufactured and assembled within our expansive northwestern New Jersey facility. Our Flex Drive family of products has made us the first name in harmonic gearing solutions.
Our Mission
We are committed to providing the widest selection of high-tech harmonic gearing components. The trusted Flex Harmonic products are backed by years of field-proven performance in very demanding applications. Our harmonic gearing and control systems have been integrated into high torque rotary cutters, robots inspecting nuclear reactors, offshore oil platform actuators, combat-tested defense communication systems, and more. We continue to develop and expand our cutting-edge product line in this consistently evolving field.
Heritage
Our harmonic gearing was first introduced to the printing industry as Conic Systems in 1968. Four years later, we pioneered the world's first harmonic differential web tension, infeed control systems. Conic Systems also invented digital HDD tension and draw control systems (1991), 1:1 HDB shaft mount harmonic differentials (1994), and 1:1 and 2:1 CSF right angle speed changing harmonic differentials (1999). In 2019, we created our LT (Lifetime Series) harmonic gearing servo gearheads.
Quality Policies
Flex Harmonic offers quality engineered solutions and industrial control for a broad range of motion control applications. Our experience translates into unmatched high-quality performing and reliable products, with units in service for decades.
Markets and Applications
Our harmonic gearing systems are widely used in aerospace, defense, medical, robotics, semiconductor, communications, solar energy, industrial automation, and electronics applications. Originally developed for space missions, harmonic gears provide compact size, high gear ratios, and precise positioning, some units even remain on the moon today. Their zero-backlash design makes them ideal for semiconductor photolithography, communication and military satellite dishes, and robotic joints that require smooth accurate motion with minimal vibration. In industrial automation, harmonic gears are increasingly valued for their compact size, high ratios, and precision across a wide range of applications. They also support solar tracking systems and thermal energy collectors by enabling smooth, accurate movement, while medical equipment and surgical robotics benefit from their quiet operation, smooth motion, and reliable high-performance positioning.
