Browning 1057165 28HP150 Timing Belt Pulley

The Browning 1057165 28HP150 Gearbelt Synchronous Timing Pulley is a Type 9, split-taper bore pulley designed for Browning Gearbelt drives. It features 28 grooves with a 1/2-inch pitch and an outside diameter of 4.402 inches, a pitch diameter of 4.456 inches, and a bore that accepts 1/2 to 1-3/4 inches. The pulley provides a 1-3/4-inch face width, a 4-11/16-inch flange diameter, a 3-inch hub diameter, and a 5/8-inch hub projection, with an overall length of 2-5/8 inches. It is intended for use with 1-1/2-inch-wide W H150 type belts, and uses a P1 bushing in a Split Taper bore configuration for secure mounting. With Gearbelt synchronous design, it delivers constant-speed, no-slip power transmission and reduced bearing loads by minimizing the need for high belt tension, making it a compact, high-precision choice for demanding belt-drive applications.
