Poly Chain® GT®2 Single-Double Sprockets

Markets/Applications
Use with Poly Chain GT2 or Poly Chain GT CarbonTM belts. Single-Doublesprockets are ideal for applications requiring multiple sprockets on asingle shaft.

Notes
Single-Double sprockets are available in stainless steel or ductile iron.
Sprocket part numbers are comprised of pitch, number of grooves and width. For example, part number SS8MX-32S-12-21 denotes “SS” for stainless steel, 8mm pitch, 32 grooves, “S” for sprocket 12mm plus 21mm width and “SD” for Single Double.
On a sprocket, pitch is the distance between groove centers and is measured on the pitch circle of the sprocket. The pitch circle of the sprocket coincides with the pitch line of the belt mating with it. The pitch diameter of the sprocket is always greater than its outside diameter.
Abbreviations used for sprocket materials: GI = Gray Iron DI = Ductile Iron SiS = Sintered Steel ST = Steel
WARNING: Do NOT use these sprockets with rim speeds in excess of 6,500 fpm.
