Browning 1002765 Qd Bushed V Belt Sheave 3 Groove

Product Description

The BROWNING 1002765 is a three-groove, QD bushed V-belt sheave designed for industrial power transmission applications. It accepts 5V, A, and B cross-section belts and features a Quick Detachable (Q1) bushing style for simplified installation and removal. The outside diameter measures 13.95 inches, with a belt pitch A diameter of 13.2 inches and a belt pitch B diameter of 13.6 inches. Bore diameter range runs from 3/4 inch minimum to 2-11/16 inch maximum, providing flexibility across a range of shaft sizes. The sheave is cast from iron for durability under continuous drive loads. Mechanical and industrial maintenance technicians install this component in motor-driven equipment requiring multi-groove belt drives.

This sheave is suited for commercial and industrial drive systems where three-belt configurations are used to transmit power from motors to fans, blowers, pumps, or compressors. The Q1 QD bushing system allows the sheave to be mounted on various shaft diameters within the stated bore range without requiring a dedicated bore machined to a fixed size. It is a common selection in HVAC air handling units, industrial ventilation systems, and pump drive assemblies where reliable belt drive performance is required.

Compatibility

Compatible with 5V, A, and B cross-section V-belts. Accepts Q1-style QD bushings within the bore range of 3/4 inch to 2-11/16 inch. Designed as a standard QD bushed sheave replacement for three-groove industrial V-belt drive applications.

Installation Notes

Installation should be performed by a qualified mechanical technician. De-energize and lock out the motor and drive system completely before removing or installing the sheave. Mount the Q1 bushing to the shaft before fully tightening fasteners, and verify belt tension and sheave alignment after installation per the drive manufacturer's guidelines. Confirm shaft diameter falls within the stated bore range before ordering the bushing.
