Browning Belt Drive BK100H Single Groove Sheave Pulley

The Browning BK100H is a BK Series cast‑iron, single‑groove pulley designed for B‑section V‑belts, delivering a rugged 9.75-inch outside diameter for reliable power transmission. It uses a split‑taper bore (H‑series bushing) that accommodates bore sizes from 3/8 to 1‑1/2 inches when mounted with the appropriate bushing. This 1‑groove pulley supports 4L, 5L, A, and B belts, with a 7/8‑inch face width and a through‑bore length around 1‑1/4 inch. Pitch diameters are approximately 9.2 inches for A belts and 9.7 inches for B belts, reflecting Browning’s BK belt designation. Cast iron construction with a gray finish provides robust durability for industrial drives, including HVAC systems and other belt‑drive installations that require reliable, long‑life pulleys in standard BK configurations.
