The PSFK Series specializes in miniature and small-diameter internal return flange single nuts. Designed for precision in compact settings, this series is the ideal solution for high-accuracy motion control where space and weight are critical constraints.

Starting from shaft diameters as small as 4 mm up to 16 mm, the PSFK series offers impressive sensitivity and low friction. Despite its compact size, it can handle dynamic loads up to 642 Kgf and static loads up to 1,315 Kgf (for 12 mm models). These ball screws are perfect for medical devices, laboratory automation, and precision electronics assembly.
