Beware
of imitators who are turning wheels out of nylon & in some cases even cheap cast resin, those wheels DO NO last, especially the crowns on the tracking & drive wheels are soon worn to a taper by the tough backing found on 2″x72″ knifemaking grinding belts! Our wheels are INJECTION MOLDED & we use
GLASS FILLED NYLON
(think fiberglass), a seriously tough material. Buy with confidence, we’ve sold thousands of these wheels over the years, they easily outlast even aluminum wheels
This listing:
1.
A set of
:
Two,
2″ diameter precision glass filled nylon idler wheels with sealed
bearings, 2-1/4″ WIDE (CHEAP WHEELS ARE 2″ WIDE).
One,
3″ diameter precision glass filled nylon tracking
wheel with sealed bearings. The tracking wheel is 2-1/4″ wide, 3″ in diameter & CROWNED (no sharp v)
to ensure accurate belt
tracking.
One,
5″ diameter precision glass filled nylon drive
wheel with aluminum core. The drive wheel is 5″ in diameter for high
surface feet per minute belt speed & crowned to ensure accurate belt
tracking, slightly dimpled to add extra grip . The face of the drive
wheel is 2-1/4″.  The set screw(included) is 1/4-20 .
Please note
that the bore of this drive wheel is
5/8″
, see our other listings if you require a drive wheel with 3/4″ or 7/8″ bore.
For
DIY style grinders like GIB, EERF, NO WELD etc. Also work
well on any professionally manufactured 2×72″ belt grinder. Made with
the exact same injection molding technology & material as used on
modern automotive engine serpentine belt idler wheels for extreme
durability & longevity under very harsh conditions. The wheels
are 2-1/4″ face width to comfortably accept any commercial 2″ wide
grinding
belt.
Bore of the bearings is 1/2″ so you can use any 1/2″ diameter bolt as an axle. The bearings are easily replaceable when worn.
We
use these wheels on the top quality grinders & flat platens that
we manufacture & our design has been thoroughly tested to withstand
even the harshest knifemaking environments!
2. D-shaped backing plate for flat platten assembly, this one with even
deeper reach for slack belt grinding. This plate is precision cnc cut
from 3/8″ hot rolled steel. Wheel mounting holes are 1/2-13 precision
tapped to ensure that axles are perpendicular to the plate. The centre
mounting hole is 1/2″ diameter, the slots for a flat platten mounting
bracket are 1/4″ wide & 6″ apart, the u-shaped adjusting slot
accepts a 3/8″ bolt or stud. The axle holes are 10.5″ center to center
apart; if you mount two 2″ diameter wheels on this backing plate you can
easily mount an 8″ long by 2-1/2″ wide flat platten between the wheels
for a large grinding surface. The rectangular spacer plate is 1/8″
thick, this effectively makes this plate 1/2″ thick through the pivot point & therefore
interchangeable with any 1/2″ thick d-plate. Have a look in our Ebay store, we have different platen mounting brackets as well as platens; ask about combined shipping.
We include 2 grade 8 bolts, 3,5″ long, 1/2-13 thread, with 4 nylon spacers, 2 1/2″ washers & 2 half-nyloc nuts.
