Nidec-Shimpo's Rotary Indexer Easily Mounts on Any Servomotor


Nidec-Shimpo’s STR Series is an off-set hollow bore rotary gearbox indexing product that is used in a variety of robotic handling applications. The STR Series can handle applications that require larger overall torque carrying capacity with a greater need for finer levels of precision. This solution for ultra-high precision obtains accuracy down to 20 arc-seconds. It allows applications to reach minor backlash, maintain excellent rigidity, and maximize control stability so the desired output motion can be easily achieved.

The utilization of a full-contact globoidal cam for high-efficiency and elimination of wear is truly a unique concept. The unit provides maximum compactness using orthogonal axes and includes a large hollow shaft for flexibility. The STR simplifies the connection to your servo motor with the incorporation of a planetary input used to achieve reduction ratios as high as 2000:1. Several frame sizes are available and it handles large, dynamic moment loads. It is a great fit for any automation, machine tool or custom material handling integrator that requires the precision, rigidity and repeatability that this servo rotary indexer offers.
