The Mini Series is a compact, lightweight unitized strain wave reducer designed for small-size applications where space, weight, and integration simplicity are critical.
This series integrates a high-precision bearing that directly supports external loads, allowing the reducer to function as a compact transmission module without the need for additional support bearings. Its optimized internal structure ensures stable performance, high stiffness, and high accuracy despite the extremely small form factor.
Leaderdrive supplies stain wave gears to industrial enterprises and research institutes around the world. If you would like to know more about our mini cup-shaped models, please contact our technical team.
