CAUTION: Many competitors are selling small wheels & holders which are narrow. They are easily identifiable by looking for a gap between the bearing & the face where the belt runs, if there’s no gap they are narrow. This means that you have zero margin for error when you track the belt & the belt often runs gouges into the sides of your holder, Careful what you spend your money on.
This listing is for a steel small wheel holder for 2×72″ belt grinders & a set of 5 small wheels.
We make the holder out of steel instead of aluminum because the hard outer
shells of the bearings eventually wear aluminum out when the small
wheels are continually removed & inserted; our bearing pockets are
also case hardened. It attaches to a tooling
arm (available separately from our Ebay store) with a 1/2-13 bolt & a 3/8-16 bolt (supplied). Finish is durable
powder coating.
For the small wheels we use 1018 steel & the wheels are surprisingly durable & grind
finger grooves precisely. The set consists of 5 popular diameters: 1/2″,
5/8″, 3/4″, 7/8″ & 1″. As with all small wheels it is important not
to spin these too fast, the bearings are too small to handle high
rpm’s. We find that a 1800rpm motor with 4″ drive wheel provides a speed
which is tolerable for moderate lengths of operating time. Keep
checking the bearings for heat even at this speed. Another excellent
option for turning these wheels slowly is our 2-Speed Lightning wheel
which has a 4:1 reduction so it turns at 1/4 motor speed (available in
our Ebay store; have a look at the Youtube video).
Higher quality
grinding belts have smooth seams which will hardly be noticeable on
these hard wheels but cheaper quality belts, especially coarse grit
belts will be bumpier than rubber or urethane coated wheels.
The bearings are replaceable & replacement bearings can be found in our Ebay store.
