Eagle NRG sprockets have been designed to insure maximum
service life and performance. Over 1,500 sprocket combinations
are available, making it easier to match the desired design speed.
More speed ratio options also means more design flexibility and
more compact drives.
Eagle NRG sprockets do not require flanges and are stocked in
ductile iron constructions. Other materials such as aluminum,
steel, and stainless steel are available upon request as made-to-
order items.

The part numbering system for Eagle NRG centers around a
color-coded sizing system for the belts and sprockets. Each belt
and sprocket part number includes a letter corresponding to a
color and is also branded in that color. The letters Y, W, P, B, G,
O and R indicate the colors Yellow, White, Purple, Blue, Green,
Orange, and Red. All Yellow belts are designed to function with
all Yellow sprockets, as is the case for the White, Purple, Blue,
Green, Orange, and Red sizes. An example of the part numbering
system nomenclature for sprockets and bushings is given below.

N om e n c l at u r e
Minimum Plain Bore, MPB: O-40S-MPB
This is an Orange size sprocket with 40 teeth and a Minimum Plain
Bore (MPB) style hub. The MPB style sprockets are supplied with
a minimum bore, typically 1⁄2˝ or 1˝ with H7 tolerances, and will
require machining of a keyway and setscrew holes, and possibly
boring to a desired bore size.
Quick Disconnect, QD: R-168S-N
This is a Red size sprocket with 168 teeth and a hub machined to
fit an “N” size QD bushing. A bushing is required to install this
sprocket on a shaft. Please note that smaller diameter sprockets are
not available in the QD style due to space limitations.
Finished Stock Bore, FSB: G-34S — 17⁄8
This is a Green size sprocket with 34 teeth and a Finished Stock
Bore (FSB) style hub featuring a bore of 1 7/8”. FSB sprockets are
supplied ready to install with a standard keyway and setscrew holes
machined.
Bored To Suit, BTS: B-28S-BTS — 1 13⁄16
This is a Blue size sprocket with 28 teeth and a hub that has been
bored (BTS) to 113⁄16˝, per customer specification, and machined
for setscrew holes and a keyway. BTS sprockets can be made to
almost any bore including metric sizes.
Note: All MPB-, QD-, and FSB-style sprockets are stock items.
BTS sprockets are made to order and may require lead times.

E 21⁄8: E Bushing Size
21⁄8Bushing Bore
Bushings are supplied with bolts, lock washers, and set screws. Keys
are supplied only if a special shallow key is required. The E 21⁄8˝
bushing can be used to install any sprocket with an “E” hub on a
21⁄8˝ shaft. The QD bushing system is an industry standard,
however, to ensure the best match between sprocket and bushing,
we recommend using bushings supplied by Veyance for Eagle NRG
sprockets.
A p p l i c at i o n s
Eagle NRG belts and sprockets are ideal for use on a
wide variety of applications in all industries.
