Notes
Belt Notes Abbreviations used for sprocket materials: GI=Gray Iron, DI=Ductile Iron, SiS=Sintered Steel, ST=Steel, CI=Cast Iron. Details shown which do not affect drive function or overall weight may be changed without notification. 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. Sprocket part numbers are comprised of pitch, number of grooves and width. For example; part number 8MX-48S-12 denotes 8mm pitch, 48 grooves, "S" for sprocket and 12mm width. Sprockets with 90 or more groves do not have flanges. WARNING: Do NOT use these sprockets with rim speeds in excess of 6,500 fpm. -

The Industry's Best.
With patented, carbon tensile cord design for high-torque, low-speed drives, Gates® engineers were the first in the world to incorporate a high fatigue-resisting carbon fiber tensile cord into the belt, which is made of a new polyurethane compound. Consequently, Poly Chain® GT™ Carbon™ quickly became the most powerful line of synchronous belts on the market, providing a maintenance-free, energy saving, and environmentally friendly operation, offering an excellent alternative to roller chain and gear drives.
Metals Made to Your Application Specifications.
With Gates® MachineWorks services, our product application experts work with you or your facility manager to customize drive components in a variety of bores, styles, materials, and finishes for your non-standard and prototype power transmission and belt drive applications.
