STR Series

str-seriesThe STR provides a solution for ultra-high precision, obtaining accuracies up to 20 arc-seconds. The STR allows an application to reach negligible backlash, maintain exceptional rigidity, and maximize control stability so that the desired output motion can be easily achieved. The design is truly a unique concept, utilizing a full contact screw-like transmission for high efficiency and elimination of wear. The unit provides maximum compactness using orthogonal axes and includes a large hollow shaft for flexibility.

The STR will most often incorporate either an inline (VRB) or right angle (EVB) reducer to achieve an additional reduction and simplify the connection to your servo motor. It is available in a number of housing sizes, and it can handle extremely large moment loads. The STR is an ideal fit for any automation or custom material handling integrator that requires the precision, rigidity, and repeatability that this servo rotary indexer can offer.
