Browning 1042522 BK67H Qd Bushed V Belt Sheave 1 Groove

Product Description

The BROWNING 1042522 is a BK67H Quick Detachable (QD) bushed V belt sheave designed for single-groove power transmission applications. It accepts standard A and B section V belts with a belt pitch A diameter of 5.7 inches and a belt pitch B diameter of 6.1 inches. The outside diameter measures 6.45 inches. Cast iron construction provides the rigidity and wear resistance required in industrial and commercial HVAC blower drives, pump drives, and general power transmission systems. The H-style QD bushing interface allows quick installation and removal without specialized tooling, making field service straightforward for mechanical contractors and millwrights.

This sheave is suited for single-groove V belt drive applications found in commercial HVAC air handling units, industrial fans, pumps, and similar rotating equipment. It accepts bore diameters ranging from 3/8 inch minimum to 1-1/2 inch maximum, making it adaptable to a range of shaft sizes commonly encountered in blower and motor assemblies. The A and B belt section compatibility broadens its use across both light-duty and moderate-duty drive configurations in residential and light commercial equipment rooms.

Installation Notes

Installation should be performed by a qualified mechanical contractor or millwright. Disconnect and lock out all power to the drive system before removing or installing any sheave. The QD bushing must be sourced separately and matched to the required shaft bore diameter before mounting. Follow the bushing manufacturer torque sequence and verify belt tension and sheave alignment with a straightedge or laser alignment tool before returning the drive to service.
