Browning 4TB154 is a TB Series four-groove V-belt sheave (cast iron) with a 15.75-inch outside diameter and a 3.25-inch face width, designed for GripBelt A and B cross-section belts. It features a split-taper bore that accepts Q1 bushings and bore sizes from 3/4 to 2-11/16 inches, enabling a true drive through a key-to-key connection. The pulley supports A and B belt pitch diameters of approximately 15.2 inches (A) and 15.7 inches (B), providing compatibility across common Browning belt configurations. All Browning B-sheaves use a combination groove that permits running A and B belts in the same pulley.
