Browning 1001502 Qd Bushed V Belt Sheave 3 Groove

Product Description

The BROWNING 1001502 is a three-groove, QD bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical systems. It accepts a P1-style QD bushing and accommodates bore diameters from 1/2 inch up to 1-3/4 inches, making it adaptable across a range of shaft sizes. The outside diameter is 4-3/4 inches, with a Belt Pitch A diameter of 4.0 inches and a Belt Pitch B diameter of 4.4 inches. Weighing 5.55 pounds, this sheave is built for reliable multi-belt drive configurations. Installation is handled by qualified millwrights, HVAC mechanics, or industrial maintenance technicians familiar with belt-drive systems.

This sheave is suited for use in air handling units, belt-driven fans, blowers, compressors, and similar rotating equipment found in both commercial and light industrial settings. The three-groove configuration supports parallel V-belt drive setups where higher torque transmission or load sharing across multiple belts is required. The QD bushing mount system allows for straightforward shaft installation and removal without specialized pulley pullers in most cases, reducing service time on routine drive maintenance.

Compatibility

Designed as an OEM-style replacement or direct-fit sheave for three-groove QD bushed V-belt drive systems using P1-style bushings, compatible with standard A and B section V-belts.

Installation Notes

Installation should be performed by a qualified technician with experience in belt-drive power transmission systems. Disconnect and lock out all power to the drive system before removing or installing any sheave or bushing. Verify that the selected P1 QD bushing matches the shaft diameter before tightening fasteners, and confirm belt tension and alignment after assembly per standard drive system guidelines. Do not operate the drive with misaligned sheaves, as this accelerates belt and bearing wear.
