Browning 2BK45H V-Belt Pulley Sheave 2-Groove

The Browning 2BK45H V-Belt Pulley Sheave is a cast-iron, two-groove belt pulley with a 4.25-inch outside diameter built for use with 4L, 5L, A, and B belt sections. It uses a BK‑H split-taper bushing bore, so the shaft bore is not fixed; a compatible H‑series bushing is installed to fit your shaft size. This dual-groove design enables load sharing across belts and is designed for quick mounting on a keyed or splined shaft via standard Browning bushing practices. The 2BK45H is part of Browning’s BK‑H family, optimized for durability and reliable power transmission in light- to mid-duty belt-drive systems. Typical applications include conveyors, fans, pumps, and other industrial equipment where a compact, two-belt drive is advantageous and precise belt alignment with a robust cast-iron pulley is required.
