21 Small-Diameter Models (under ø16) Standardized in Anticipation of Growth in Demand

Miniature ball screw is a general term that refers to small-diameter size ball screws with a shaft diameter of ø16 and below. They have traditionally been used in a wide range of applications for small equipment, possessing features that can only be obtained from miniature products.

Recently, the environment surrounding the ball screw has changed significantly. Particularly for semiconductor manufacturing equipment, electronic component mounting machines, and medical equipment, demand is expected to grow greatly for small-diameter ball screws, and there are many requests for standardization.

To meet the needs of its customers, THK is adding five screw shaft diameters (ø6, ø8, ø10, ø12, and ø14) and nine lead sizes (1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 8 mm, and 10 mm) to the lineup as standard catalog products, creating a total of 21 models through screw shaft diameter and lead combinations.

THK contributes to the performance of a wide range of equipment, from general industrial machinery to precision machinery and compact, high-precision machine tools.
