Harmonic Gearhead

Harmonic Gearheads

Conic Systems offers a line of zero-backlash, single stage gearboxes with ratios ranging from 50:1 to 160:1. With competitive size and performance, these harmonic gearboxes provide a superior alternative to standard planetary gearboxes, while allowing for accuracies unmatched by traditional gearing. The gearboxes are available in NEMA standards, as well as having metric output options. Alternative input and output designs can be produced upon request, contact Conic Systems for availability.
