Drive Pulleys are listed for OEM's as they are built to
order
and require minimum volumes per part number.
These Don
Dye drive pulleys are designed for consistent quality.
We do not stake, copper braze or spot weld. The pulleys
are formed on compound dies designed and built in our
plant and held to much closer tolerances than would
normally be considered necessary. The halves are then
riveted together and the hubs welded in by mig welders
on turning and holding fixtures designed and built in
our plant for this express purpose. They require no
balancing and are easily adapted to standard or special
uses. In many instances these pulleys have proved strong
enough to replace cast pulleys resulting in considerable
cost savings to the manufacturer and consumer.
We believe you will find this to be the strongest and
most dependable line of riveted pressed steel drive
pulleys on the market today.
Standards
When ordering standards please remember the sheave
itself is 14 gauge and has the same part number
regardless of hub design. Our standard hubs with part
numbers listed below have a keyway and two set screw
holes tapped with N.C. threads . Please order pulley

There are many other hubs available, special bore sizes,
splines, tapers etc.
Specials
are produced in 14 gauge, 13 gauge and 11 gauge with
many combinations of hub lengths and bores to 1 1/2"
diameter. Hubs are machined from 2", 2 1/8" and 2 1/2"
diameter steel bar stock. Bores can be tapered with
keyways, tapered keyways, broached splines, hex bores,
metric bores or dimensions, pin holes or any number of
special shapes and combinations. The pulleys can be
trimmed and mounted on the same hub for step cone effect
or speed change, also with double row ball bearing hubs.
Most of
these pulleys are available with 6 1/2" diameter flat
area in the center for punching a bolt hole arrangement
to bolt on customer's hub. We are continually tooling
additional sizes.
