Browning 1001791 Qd Bushed V Belt Sheave 2 Groove

Product Description

The BROWNING 1001791 is a two-groove, QD bushed V belt sheave designed for industrial belt drive systems. Built from cast iron, it accepts standard A and B section belts as well as 5V belts, with a belt pitch A diameter of 5.0 inches and a belt pitch B diameter of 5.4 inches. The outside diameter measures 5.75 inches. The QD (Quick Detachable) bushing interface uses a P1 bushing style, allowing fast installation and removal without specialized tooling. HVAC equipment technicians and industrial maintenance pros install this sheave on blower and fan drive assemblies where precise belt alignment and secure shaft engagement are required.

This sheave fits blower fan drive applications common in commercial and light industrial HVAC systems, as well as general-purpose belt drive machinery. It accommodates bore diameters from 0.5 inches up to 1.5 inches, making it compatible with a range of shaft sizes typically found in air handler blowers, exhaust fans, and similar rotating equipment. The two-groove configuration suits dual-belt drive setups where load sharing or redundancy is needed.
