Browning 1042514 Qd V-belt Sheave 1 Groove 6.25 in Od

Product Description

The BROWNING 1042514 is a quick-detachable (QD) bushed V-belt sheave designed for single-groove power transmission applications. Carrying the BK65H designation, it accepts an H-style QD bushing and accommodates bore diameters from 0.375 inches up to 1.5 inches, making it adaptable to a wide range of shaft sizes without machining. The 6.25-inch outside diameter sheave is cast from iron for durability in demanding industrial and HVAC drive systems. It is sized for A and B cross-section V-belts, with a belt pitch diameter of 5.5 inches for A-section belts and 5.9 inches for B-section belts. Mechanical contractors, industrial maintenance technicians, and HVAC installers commonly specify this sheave for blower, fan, and pump drive assemblies.

This sheave is suited for both commercial and industrial drive applications including air handling units, centrifugal fans, blowers, and pump systems where a single-groove V-belt drive is required. The QD bushing system allows for straightforward installation and removal on standard keyed shafts, reducing downtime during scheduled maintenance. Its compatibility with both A and B belt sections provides flexibility when replacing or upgrading existing drive configurations in the field.

Installation Notes

Installation should be performed by a qualified mechanical or HVAC technician. Disconnect and lock out all power to the drive system before beginning work. Ensure the mating H-style QD bushing is properly seated and fasteners are tightened evenly in a cross pattern before applying belt tension. Verify belt alignment and tension after installation to avoid premature wear.
