Regal Beloit Corporation 1B38SH Belt Pulley Sheave

Regal Beloit’s Browning 1B38SH is a single‑groove V‑belt pulley (SH series) with a 4.15" outside diameter and a bushing‑style bore, designed for use with A‑ and B‑section belts in compact drive settings. It features a 0.875" face width and cast‑iron construction for durability, with two pitch diameters depending on belt type: 3.60" for A‑section belts and 4.10" for B‑section belts, enabling precise belt length and speed ratios in shared shaft setups. The SH bushing bore accepts shaft sizes from 1/2" to 1-5/8" (Type D1 configuration), providing a reliable fit across common small‑to‑mid power drives. This pulley is appropriate for Regal Rexnord Browning belt drive assemblies and is used wherever a robust, one‑groove pulley is required for standard V‑belt drives.
