Browning 3X871 BK36 Single Groove Pulley 1 Inch Bore

The Browning BK36X1 is a finished-bore, single-groove V-belt pulley cast in durable iron for dependable belt drives. It features a 3-3/4" outside diameter, a 1" finished bore for direct mounting on a 1" shaft, and a 7/8" wide face for stable belt contact. This Type 2 BK36X1 delivers broad belt compatibility, supporting A-, 4L-, B-, and 5L-series belts to suit common drive configurations. For belt-pitch reference, it provides approximately 3.2" pitch diameter with A-belts and 3.7" pitch diameter with B-belts, depending on the belt section used. The cast-iron construction helps resist wear and vibration in HVAC and light-industrial belt-drive applications, while the finished bore ensures concentric mounting and reliable operation. Typical uses include small motor-driven drives such as blowers, pumps, conveyors, and machine tools where a compact single-groove pulley is required. As part of Browning's BK series, it offers interchangeability with other BK36-family sheaves while maintaining a 7/8" face width to fit standard belt-sheave assemblies.
