Gates® Power Transmission Poly Chain® GT®2 8MX-112S-62 Synchronous Sprocket, 7/8 to 3-1/4 in Taper-Lock® Bore, 11.17 in OD, 112 Grooves, 11.229 in Dia Pitch, 2.91 in W Face
Poly Chain GT sprockets use the tooth profile designed and developed by Gates and function with Gates Poly Chain GT belts in all existing constructions. These sprockets are statically balanced to make sure the entire belt drive is as safe as possible. Furthermore, they are manufactured, specified, and tested to perfectly support the full power capabilities of the Gates Poly Chain belt product range. Belts and sprockets used together get the best out of your belt drive: maximum performance, prolonged antistatic properties and optimal lifetime.

Sure-Grip® quick detachable bushings are easy to install and remove. Split-through flange and taper provide a true clamp on the shaft that is equivalent to a shrink fit. All sizes except JA and QT have a set screw over the key to help maintain the bushing's position on the shaft until the cap screws are securely tightened. Versatile Sure-Grip® bushings permit the mounting of the same mating part on shafts of different diameters and the mounting of different sheaves on the same shaft using the same bushing.

Give yourself a competitive advantage by designing in the Gates Poly Chain™ GT™ Carbon drive system instead of roller chain in your next power transmission application. The patented use of carbon fiber as the tensile cord in this belt provides increased horsepower rating for greater power density and compactness. When combined with Gates Poly Chain GT sprockets, you have a lightweight, long-lasting, maintenance-free system that's more than a match for roller chain.
