The
NB Slide Shaft was developed to achieve greater accuracy
in roundness, cylindricity, surface finishing, and
linear travel. Heat treated in both axial and radial
directions, NB Slide Shaft come in both high-carbon
chromium bearing steel or Martensite stainless steel
for maximum performance quality. In addition, our
precision machining capabilities offer you a variety
of specially engineered custom shafts, such as spindle
and roll shafts, to meet your special requirement.
NB Slide Shafts feature reliable, high precision
roundness cylindicity, straightness, and surface finish.
Fig. 1 and 2 show examples of measurement results
for roundness and surface finish, respectively.
Heat Treatment
NB Slide Shafts are annealed, quenched and tempered
by processing techniques and skills developed by .
The heat treatment assures the Slide Shafts uniform
hardness in both radial and axial directions, developing
an appropriate layer. The Martensite stainless steel
(SUS 440C) is also subjected to a sophisicated heat
treatment to suppress distortion, assuring a uniform
hardened layer and sufficient hardness. |
