Miniature Metric Ball Screws
Thomson miniature metric ball screws accomplish this with a unique multi-liner return system that maximizes the number of circuits and loaded balls in the nut. A miniature metric system with a multi-liner return system, for example, deploys 168 balls in eight circuits to support 7.6 kN of static load, as compared to a single-liner design, which would use 84 balls in four circuits to support only 4.2 kN.
