Sprocket combinations to fit your
drive system’s needs
SilentSync® sprockets have been designed to ensure
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.
SilentSync® 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.
Matching belt to sprocket has never
been easier
The part numbering system for SilentSync® 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.
Sprocket part number nomenclature
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 inch or 1 inch 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 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 – 1⅞
This is a Green size sprocket with 34 teeth and a Finished Stock
Bore (FSB) style hub featuring a bore of 1⅞ inches. FSB
sprockets are supplied ready to install with a standard keyway
and setscrew holes machined.
Bored To Suit
(BTS)
B-28S-BTS – 1
n
This is a Blue size sprocket with 28 teeth and a hub that has
been bored (BTS) to 1
n
inches, 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.
Bushing part number nomenclature
E 2⅛
E
Bushing size
2⅛
Bushing bore
Bushings are supplied with bolts, lock washers and set screws.
Keys are supplied only if a special shallow key is required. The E
2⅛ inch bushing can be used to install any sprocket with an “E”
hub on a 2⅛ inch 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
Continental ContiTech for SilentSync® sprockets.
Applications
SilentSync® belts and sprockets are ideal for use on a wide
variety of applications in all industries.
