About

Harmonic Drive® CSF-2UP gear units are housed, zero-backlash strain wave gears equipped with a precision output bearing. These new models are designed to be lightweight and extremely flat, making them ideal for applications where space and weight are critical. Thanks to a cross roller bearing used at the output flange, the CSF-2UP gearheads offer high-moment stiffness, ensuring stable and precise operation. The CSF-2UP mini gearheads are ideally suited for small robots or equipment requiring an ultra-compact solution, providing high positioning accuracy and high torque capacity. They also boast high radial, axial, and moment load capacity, with available ratios ranging from 30:1 to 100:1.
