The CSF-2UP gear units are the newest models in the CSF mini-series lineup. These new gear units have an ultra-flat configuration with high-moment stiffness. Harmonic Drive® gear units are housed, zero-backlash gears with a precision output bearing. The new models are lightweight and extremely flat. Thanks to a cross roller bearing used at the output flange, the CSF-2UP gearheads offer high-moment stiffness. The CSF-2UP mini gearheads are ideally suited for small robots or equipment requiring an ultra-compact solution.
