Chain and Sprockets
Sprockets are not Gears, Gears mesh together directly to distribute power. Sprockets are not pulleys,pulleys  are smooth
and pulleys utilize belts to convey power. Sprockets are used with Chain and the center distance between the two the
sprockets can variey in distance. The advantage of using sprockets and chain is that slippage is not admissible. A higher
degree of torque can be used with sprockets chain but slower Rpm's.  Pulleys and belts disadvantage is the slippage
factor, but the components are much lighter and can run  at a higher RPM.  There are some HTD Belts and Pulleys  that
will give you both the advantage of High torque and High Rpm. Sprockets and Chain are more cost effective and  very
accessible power transmission options. There are a large variety of Sprockets and  that can meet
all different applications.

Sprockets
Double Single
Sprocket
Type C Style has a
double hub to give it
more stability
Sprockets come in QD
style also for
installation and
removal ease
Idler sprockets are
used to take up chain
lag or it can used for
chain return
Split hubs are round and fully
machined. They do not have
dangerous projecting bolts or
ears. They are drilled and
tapped for high strength
socket head cap screws and
are welded to each side of a
Type A sprocket, forming a
unit similar in appearance to
a Type C sprocket. Fully split
sprockets cost more to
produce than solid, but may
provide significant cost
savings by simplifying
installation and removal
