Industrial lock nuts with lock washers are not considered to be suitable for super-precision bearing applications because of the relatively wide manufacturing tolerances of the thread and abutment surfaces. As a result, SKF has developed a full line of precision lock nuts that are manufactured within very tight tolerances. These simple to mount devices, which locate bearings and other components accurately and efficiently on a shaft, meet the requirements of machine tool applications, both technically and economically.

All SKF precision lock nuts use friction between the mating thread flanks of the spindle shaft and lock nut to hold them in place. To apply this friction, SKF manufactures precision lock nuts in the following design:

Machine tools require screw drives that can position a work piece or machine component quickly, efficiently, and precisely. To meet these requirements, screw drives can be supported at both ends by SKF super-precision angular contact thrust ball bearings. The bearings provide a high degree of axial stiffness, high axial load carrying capacity, accommodate high speeds and rapid accelerations, and offer very high running accuracy.

Angular contact thrust ball bearings for screw drives are well suited for screw drive applications, but are also beneficial in other applications, where reliable radial and axial support is required, together with extremely precise axial guidance of the shaft.
