Browning 3TA50 Sheave Bearing

Browning 3TB50 3-Groove V-Belt Sheave is a cast-iron pulley designed for Browning belt-drive systems, Type 13 Web, with three V-groove surfaces for multiple-belt drives. It features a 5.35 inch outside diameter and a 2-1/2 inch face width, providing compact torque capacity for mid-size drives. Mounting is by Browning split-taper bushings (P1), with a bore range of 1/2 to 1-3/4 inches, enabling a secure fit on common shafts. The pulley provides A- and B-belt pitch diameters of 4.8 inches and 5.3 inches, aligning with Browning's A and B belt families and standard power-transmission specifications. Constructed in cast iron for rigidity and long service life, the 3TB50 is intended for moderate horsepower belt-drive applications across industrial equipment and conveyors. This Type 13 Web configuration helps ensure stable belt tracking and efficient power transfer during frequent starts and stops in typical industrial duty cycles.
