Double-pitch Roller Chain Sprockets-S Type

The number of teeth of the sprocket is determined so that the chain meshes with one of every two teeth of sprocket per turn of the sprocket.This number of teeth is termed "number of working teeth".

In case of odd number of teeth,each tooth of the sprocket meshes wish the chain per two turns of the sprocket,thus extending service life of the sprocket.

Notes:*Bottom diameter for even number of teeth,Caliper diameter for odd number of teeth.
