KSS PSR/PSRT Series Rolled Ball Screw

The KSS PSR/PSRT Series Rolled Ball Screws achieve high accuracy to JIS C5 grade through advanced rolling processes, narrowing the performance gap that typically exists between rolled and ground ball screws.

They offer high precision with excellent cost performance, making them a practical replacement for conventional C5 grade ground ball screws in applications where the higher manufacturing cost of grinding is not justified by the application’s actual accuracy requirements. This positions the PSR/PSRT Series as a cost-effective alternative for precision motion applications that previously required ground ball screws to meet C5 grade tolerances.
