4 Superb durability

NSK uses thoroughly purified alloy steel, and applies

special case hardening heat treatment to it for

superb durability.
 

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.
