5 No backlash, and unparalleled rigidity
NSK ball screws use gothic-arch groove as shown in
Fig. I-1.1. Providing controlled preload is easy, thanks
to this gothic-arch groove, and appropriate rigidity
with no backlash can be obtained. As the Gothic-arch
also minimizes the clearance between the balls and
the groove, the back lash is controlled to minimal
without applying preload.
