Browning 1002468 Qd Bushed V Belt Sheave 3 Groove

Product Description

The BROWNING 1002468 is a three-groove, QD bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It accepts a Q1-style quick-detachable bushing with a bore range of 3/4 inch to 2-11/16 inches, allowing for flexible shaft sizing without a custom fit. The outside diameter measures 8.95 inches, and the belt pitch A diameter is 8.2 inches, with a belt pitch B diameter of 8.6 inches. Constructed from iron, this sheave is built to handle the repeated loading common in belt-driven fan and blower assemblies. Licensed HVAC technicians, millwrights, and mechanical contractors are the typical installers.

This sheave is suited for residential and commercial belt-drive systems where 5V, A, or B cross-section V-belts are used. Common applications include air handling units, belt-driven blowers, cooling tower fans, and industrial drive assemblies that require a multi-groove sheave to transmit load across parallel belt runs. The three-groove configuration helps distribute drive load evenly, reducing wear on individual belts and extending service intervals in continuous-duty equipment.

Installation Notes

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