About

The CSG-2UH is a high torque housed component gear set combined with a precision cross roller output bearing & flange. It is a very compact, robust and easy to use gearhead solution. The CSG-2UH is available in 10 sizes with ratios 30:1 to 160:1. If your application does not require high torque, CSF-2UH standard torque gearhead is a great alternative gearhead. There is also a lightweight version, CSG-2UH-LW for applications where weight is a critical factor. Key features include zero backlash, peak torque ranging from 23Nm to 3419Nm, and accuracy less than 1 arc-min. It offers high torsional stiffness, high efficiency, and smooth operation, along with a robust cross roller output bearing and an output flange for direct mounting of the load.
