Ball screws with interchangeable nut-shaft combinations

NSK is releasing a new series of ball screws in which the nut and shaft can be freely combined. This design makes it easier for both dealers and end users to stock or purchase high quality ball screws in small batches.

The new ball screw does not require using an individually matched nut-shaft combination. Instead, the nut and shaft can be freely interchanged, following the principle of random matching.

Available in accuracy class C7, the ball screws come in shaft diameters from 15 to 32 mm, with pitches from 5 to 20 mm. Thanks to their inherent design, the units are shipped with very little axial play as standard. If necessary, a desired preload can be generated by changing the size of the balls at a NSK dealer or directly at NSK.

The new series is ideal for applications that include pick-and-place systems, as well as automated transfer units for assembly, handling and internal transport. Many other uses are also possible.

For users, the free interchange of nut and shaft has the advantage that the required ball screw can simply be taken or ordered from stock, and then cut to length either in-house or by an authorised NSK dealer.
