Browning BK65X1 FHP CI F Sheaves

The Browning BK65X1 FHP CI F Sheave is a fixed-bore, single-groove cast-iron V-belt pulley designed for BK-series belt drives that run 4L, 5L, A, or B belts. It uses Browning’s finished-bore (FHP) design with a 1" bore and a 6.25" outside diameter, and it requires no separate bushing for mounting. The pulley presents an overall width of 1.2813" and a face width of 0.875", with a 1/4" keyway to secure it to a shaft. Its pitch diameters are 5.7" for the A-section and 6.2" for the B-section, while datum diameters are 5.5" (A) and 5.9" (B) to ensure correct belt seating and alignment. Cast from iron, the BK65X1 weighs about 3.24 lb and is part of Browning’s BK fixed-diameter, finished-bore family, optimized for light- to mid-duty industrial drives such as conveyors and other machinery that utilize standard A/B belt sections. This 1-groove configuration supports a range of Belt Sections and is suitable wherever precise, interchangeable pulley sizing is required for BK-series belt drives.
