Browning 28XHR200 Keyed Pulley Sheave 8 Inch Bore

The Browning 28XHR200 timing pulley is a 28-groove gearbelt pulley designed for synchronous belt drives. It features a 7.689-inch outside diameter and a belt pitch diameter of 7.799 inches, with a 2-9/16-inch face width that supports stable belt alignment and torque transmission. The designation 28XHR200 identifies a Type 11 pulley with a bore capable of accommodating common Browning hub configurations, typically ranging from 1-1/8 to 3-3/4 inches in diameter; options include a split-taper bore or a bushed bore (R1) install, depending on the exact hub style ordered. This versatility allows secure mounting on a wide range of shafts while preserving accurate belt engagement and minimal slip in demanding applications. Common uses include conveyors, packaging lines, and other automated equipment where a 28-tooth synchronous pulley pairs with a matching Browning belt to achieve reliable speed ratios and consistent performance. The 28XHR200 is offered in stock Browning configurations and is compatible with Browning’s Type 11 pulleys and associated hubs, making it a solid choice for both new installations and retrofits that rely on Browning timing-pulley geometry.
