GTC BEARING SYSTEM PIVOT PINS
GTC
440C stainless steel thrust ball bearings
caged in stainless steel retainers developed
and patented by
Gustavo T. Cecchini's GTC
Knives
to reduce friction and failures, increase
opening time, and easier cleaning. The 100%
stainless steel construction eliminates the
problems of other thrust bearings that are not
100% stainless. Install by cutting a pocket,
with a counterbore, in both the blade and
frame. Use one bearing in blade and one
in the frame. Some prefer to cut the pocket
in both frames, and not in the blade. This is
a good solution when the blade is already
hardened. Sold Each.
The Path Maker is used to provide a smooth
raceway for the thrust bearing balls to slide
along. The Path Maker is used in a drill
press to mark the raceway into the blade and
liners. This task is performed by setting your
drill press at 500 RPM and applying a light
down pressure for a few seconds. Check the
surface for marking until a circular raceway
is visible, then this task is complete. We
recommend that you complete this task to the
blade before and after heat treat to guarantee
the elimination of all tooling marks. You will
need a different Path Maker for each bearing
size and each pivot size that you use. The
final assembly should use new bearings only.
A bearing will be included with each Path
Maker.
The illustration (above left) shows the pocket
in the left liner once the procedure has been
completed. The first bearing will fit in this
pocket. The second pocket should be cut in
the blade. In final assembly (see above right),
the liner pocket and blade pocket should
be facing up when the knife is in the proper
position for assembly.
There should be a
raceway path on each
side of a thrust bearing.
The illustration above
shows the right liner
with
the
raceway
path completed. This
raceway matches up
to the blade pocket
thrust bearing. This procedure should be
completed on both sides of the blade. This
will match up with the raceway needed in the
liner pocket thrust bearing. When finished
you will have made a raceway path on all four
bearing surfaces and you should be ready for
assembly.
Quality, high speed steel counterbores used
to set your GTC bearing system. Select the
counterbore for your chosen size (outside
diameter of the bearing). Then choose the
pilot to fit the shank diameter of your pivot
pin. Proper cutting depths are .050" for all
bearings except GC102 with a cutting depth
of .066".
Reamers are .0005" oversize. Ream blade
and liners for pivot pins.
