Browning® Gearbelt® 1056555 Type 4 Synchronous Timing Pulley With Flange, 3/8 to 1 in Split Taper Bore, 2.477 in OD, 21 Grooves, 2.507 in Dia Pitch, 1-1/4 in W Face
Synchronous belt drives help reduce the problems of slippage, belt stretch, lubrication and metal to metal contact. They provide superior performance because power is transmitted by positive engagement of belt teeth rather than by friction, as in conventional belt drives.

Gates® Power Transmission PowerGrip® GT®3 1760-8MGT-12 Synchronous Belt, 12 mm W, 1760 mm OAL, 8 mm Pitch, 220 Teeth, Neoprene
Engineered with the latest in advanced technology and materials science expertise, Gates PowerGrip™ GT4 delivers the highest power-carrying capacity of any belt in its class. In addition, Gates designed a belt with increased chemical resistance and larger temperature range capability. Gates PowerGrip GT4 belt delivers improved performance over a wide range of industrial applications. The 8MGT and 14MGT pitches are the optimum choice for high performance drives in the machine tool, paper and textile industries where durability and low maintenance are required. From resource processing to heavy manufacturing, automated production to custom assembly — Gates PowerGrip GT4 solutions improve uptime, efficiency, productivity, reliability and safety for industries around the world.
Gates® Power Transmission Poly Chain® GT® Carbon™ 8MGT-2240-36 Synchronous Belt, 36 mm W, 2240 mm OAL, 8 mm Pitch, 280 Teeth, Polyurethane
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.
