"Premium Strain Wave Gears"
US supplier of precision strain wave (harmonic) gears with zero backlash and high torque density for robotics and automation OEMs.
Quad A Research Labs is a US-based supplier of precision strain wave gears (harmonic drives) serving engineers and OEMs across North America. The company sources strain wave gears manufactured in Taiwan and supplies them to the North American market for use in robotics and automation applications. Its core product lines are the PCS (cup type) and PSH (hollow shaft) series, offered in frame sizes 14 through 32, with standard reduction ratios of 50:1, 80:1 and 100:1.
Beyond the catalog range, the company offers custom reduction ratios from 30:1 to 160:1, modified output shafts, and special mounting configurations on request, allowing the gears to be tailored to custom mechanical assemblies. The strain wave gears are characterized by high torque capacity, zero backlash and a compact, lightweight form factor, properties that make them well-suited to robot joints, actuators and precision motion stages where accuracy and repeatability are critical. Quad A Research Labs positions itself as a responsive component-supply partner, stating that its team responds to quote requests within one business day. As a motion-component specialist focused on harmonic gearing, the company supports robotics, collaborative robots, and automation system builders that require backlash-free speed reduction in confined spaces.
