Ball Screw Assemblies Including Miniature Linear Actuators

Miniature ball screw assemblies consist of a compact screw shaft and matching nut with precision helical grooves that recirculate ball bearings, converting rotary motion into smooth, low-friction linear motion. Designed for small-scale automation, positioning, and motion control applications, these assemblies are available with 1 mm, 2 mm, and 2.5 mm lead sizes and screw diameters of 6 mm, 8 mm, and 10 mm. The 1050 steel screw is precision rolled in the US for accuracy, consistency, and reliable travel, with flanged nut and cylindrical nut configurations available to support different mounting requirements. Compared with lead screws, miniature ball screws require less than one-third the torque, making rotary-to-linear motion transfer easier and more efficient in compact systems. They are compatible with NEMA 08, 11, 14, 17, and 23 motor frame sizes, giving designers flexible options for integrating precise linear motion into space-constrained assemblies.
