Browning 2BK90X1 Pulley Sheave Factory Sealed

Browning 2BK90X1 is a fixed-pitch, two-groove V-belt pulley in the BK-series, cast iron for durability in fractional-horsepower drives. It uses a finished 1" bore with a 0.25" keyway and accepts 4L, 5L, A, and B belts, providing multiple cross-section options in one part. With an outside diameter of 8.75" and a face width of 1.75" (overall width 2.0938"), the 2BK90X1 also features datum diameters of 8.000" (A) and 8.400" (B) and pitch diameters of 8.200" (A) and 8.700" (B), enabling precise alignment for paired-belt drives. The through-bore length is 1.5938" and the pulley weighs about 9.29 lb, making it a substantial yet compact choice for belt-drive assemblies. Commonly used in HVAC equipment and light industrial machinery, this Browning sheave provides reliable operation in two-belt configurations and pairs with fixed-pitch cross-section belts for straightforward maintenance and replacement.
