Browning 4TC82 4-Groove Sheave With 4-Inch Bore

Browning 4TC82 is a four-groove TC-series V-belt pulley (sheave) cast in close-grain iron for dependable power-transmission drives. It features an 8.6-inch outside diameter and an 8.6-inch pitch diameter with four grooves sized for Browning C-belt cross-section belts, ensuring even load distribution across belts. The bore is not fixed; it accepts Browning Split-Taper bushings to fit a shaft bore from 1 inch up to 2-5/8 inches, with a standard 1/4 x 1/8 inch keyseat to secure the pulley on the shaft. The 4TC82 configuration is commonly found in Q2/bushed variants, reflecting Browning’s interchangeable-bushing approach for quick bore changes. Made from close-grain cast iron, this pulley provides the rigidity and dimensional precision needed for reliable belt alignment in fixed-pitch drives. This configuration helps maintain belt alignment and even load distribution across all four belts, and is typically used in Browning V-belt drive systems where a four-groove arrangement is desired for reliable power transmission in conveyors and other industrial equipment.
