Browning 2BK32X1-1 4 Sheave Dual Groove Pulley

The Browning 2BK32X1-1 dual‑groove, finished‑bore pulley is a cast‑iron BK‑series V‑belt sheave configured for two belts in a single unit. It accepts four belt sections—4L, 5L, A, and B—and provides two pitch diameters: 2.800 in (A) and 3.300 in (B), enabling flexible speed ratios. With an outside diameter of 3.350 in and a face width of 1.750 in, the pulley carries a 1-1/8 in bore and a 1/4 in keyway; the bore is finished and its design is Not Required for a separate bushing, simplifying mounting on standard shafts. The overall width is 2.2188 in and the part weighs 2.27 lb, making it suitable for compact, high‑torque belt drives in power transmission applications. As a combination‑groove design, all Browning BK sheaves permit running A, 4L, B, and 5L belts to achieve different pitch diameters and horsepower ratings.
