Browning 2BK90H Two Groove Timing Pulley Hub Assembly

Browning 2BK90H is a fixed-pitch, two-groove cast-iron V-belt pulley intended for use with Browning H-series bushings. It features an 8.75-inch outside diameter and weighs about 7.96 lb, providing a solid hub platform for power-transmission drives. The 2-groove design accepts belt sections 4L, A, 5L, and B, enabling two fixed ratios in a single compact pulley. A separate H-series bushing is required for mounting on a shaft; Browning catalogs this model under the Pulleys & Sheaves family, with manufacturer part number 1043116 corresponding to the 2BK90H entry. This pulley’s rugged cast-iron construction and dual-groove arrangement suit drives requiring reliable, fixed-pitch operation in industrial equipment where space is at a premium.
