Browning 1042555 Qd V-belt Sheave 1 Groove 7.25 in Od

Product Description

The BROWNING 1042555 is a single-groove, quick-detachable (QD) bushed V-belt sheave designed for power transmission applications in HVAC, industrial fan, blower, and pump drive systems. Built from cast iron, this sheave features an H-style QD bushing interface that allows fast installation and removal without special tooling. The outside diameter measures 7.25 inches, with a belt pitch A diameter of 6.5 inches and a belt pitch B diameter of 6.9 inches. It accepts bore sizes from 0.375 inches up to 1.5 inches, making it compatible with a wide range of shaft configurations. Licensed HVAC technicians, millwrights, and mechanical contractors typically install this component during blower assembly or belt drive system service.

This sheave is suited for use in commercial and residential HVAC air handling units, industrial blowers, fans, and other single-groove belt drive assemblies where A or B profile belts are specified. The H-style QD bushing mount makes it a practical choice when frequent shaft removal or sheave repositioning is part of scheduled maintenance. The 7.25-inch outside diameter and 1-groove configuration are commonly found in rooftop unit fan drives, air handler blower sections, and belt-driven pump setups.

Installation Notes

Installation should be performed by a qualified technician or millwright. Disconnect and lock out all power to the drive system before beginning work.
