Synchronous Belts
INSTALLATION GUIDE

MATCHING BELTS
Drives using synchronous belts are not recommended to
run in matched sets. If a special application requires
matching, specify “matched belts” on the order. Note:
such requests require additional order lead time. Also,
matching code numbers will not appear on the belts.
HOW TO INSTALL BELTS
Before installation, inspect the belt for damage. Belts
should never appear crimped or bent to a diameter less
than the minimum recommended sprocket diameter.
Always move the drive unit so you can easily slip the belts
into the grooves without force.
Shorten the center distance or release the tensioning idler
to install the belt. Do not pry the belt on the sprocket.
Refer to the following Center Distance Allowance tables for
the required center distance adjustment.
Place the belt on each sprocket and ensure proper
engagement between the sprocket and belt teeth.
Lengthen the center distance or adjust the tensioning idler
to remove any belt slack.

If you install a belt over one fanged sprocket and one unfanged
sprocket with the sprockets already installed on the drive, allow the
following decrease in center distance for installation and increase
in center distance for tensioning.
Apply the following center distance allowances for Hawk Pd® and
Falcon HTC®. A center distance adjustment, or decrease in
center distance, is necessary to install a belt. In addition, an
increase in center distance will be necessary for proper tensioning.
If you install a belt together with sprockets, allow the following
decrease in center distance for installation and an increase in
center distance for tensioning.
If you install the belt over two fanged sprockets that are
already installed on the drive, allow the following decrease in
center distance for installation and increase in center distance for
tensioning.
Consider the following center distance allowances when installing
Eagle NRG™ sprockets.
Since fanges are not necessary on Eagle NRG™ drives, only one
table of center distance allowances is provided.
