Browning 2TB64 Sheave

The Browning 2TB64 TB Gripbelt® Double-Groove Bushed Sheave is a cast-iron, two-groove V-belt pulley designed for A- and B-section belts, with a 6.75-inch outside diameter and webbed construction for rigidity. It uses Browning’s split-taper P1 bushing system, accepting shaft bores from 0.500 to 1.750 inches and providing a through-bore length of 1.9375 inches with a 0.375-inch keyway for secure mounting. The pulley supports two pitch diameters: 6.20 inches for A-belts and 6.70 inches for B-belts, with datum diameters of 6.00 inches (A) and 6.40 inches (B) to aid proper alignment. Overall width is 2.1875 inches and face width 1.75 inches, with a weight around 8.45 pounds and metal: cast iron. This unit is explicitly listed as a 2-groove, bushed pulley compatible with Browning P1 bushings, making it suitable for light- to medium-duty power transmission tasks where A- or B-series belts are used. The 2TB64 is commonly employed in drives requiring a fixed-pitch, two-groove configuration and can be paired with Browning’s TB Gripbelt bushing assemblies to achieve precise shaft and hub engagement.
