Browning BK85H Sheave

Browning BK85H is a one-groove cast-iron pulley in the BK H series, intended for fixed-pitch V-belt drives. This bushed, single-groove BK85H supports 4L/A and 5L/B belt profiles and uses a split-taper bore that accommodates shaft sizes from 3/8" to 1-1/2" with Browning Split-Taper bushings for secure mounting. The pulley has an 8.25" outside diameter and a 7/8" wide face, providing a compact yet rigid seating surface for the belt. Its pitch diameters are 7.7" for A (4L) belts and 8.2" for B (5L) belts, enabling drive configurations within the BK H family to cover multiple ratios without changing pulleys. Cast iron construction delivers rigidity and stable belt alignment in industrial belt-drive assemblies. The BK85H is configured as a 1-groove BK H sheave, suitable for single-belt drives in equipment that relies on dependable, fixed-pitch belt systems. This model aligns with Browning’s BK H lineup, supporting consistent center distances and proven compatibility across standard BK H configurations.
