Structure and Features

Combinations of Various Shaft Diameters and Leads

You can select the combination of a shaft diameter and a lead that meets the intended use from the various nut types and the screw shaft leads. Those nut types include the return-pipe nuts, which represent the most extensive variations among the series, the compact simple nuts, and the large-lead end cap nuts.

Screw Shaft Standard Products (Unfinished Shaft Ends/Finished Shaft Ends) Available

The unfinished shaft end types, which are mass-produced by cutting the standardized screw shafts to fixed lengths, and those with finished shaft ends, for which the screw shaft ends are machined to match the corresponding support units, are available as standard.

Accuracy Standards Compliant with JIS (ISO)

The precision of the ball screw is controlled in accordance with JIS B 1192 (ISO 3408).
