Browning 1042415 Qd Bushed V Belt Sheave 1 Groove

Product Description

The BROWNING 1042415 is a single-groove, QD bushed V belt sheave designed for use in belt-driven mechanical power transmission systems. Manufactured from iron and carrying the BK36H designation, this sheave features a 3.75-inch outside diameter and accepts H-style QD bushings across a bore range of 0.375 inches to 1.5 inches. It is compatible with both A and B section V belts, with a belt pitch A diameter of 3.0 inches and a belt pitch B diameter of 3.4 inches. Millwrights, HVAC technicians, and industrial mechanics install this type of sheave on fan shafts, blower assemblies, and general-purpose drive systems where quick-disconnect bushing mounting is required.

This sheave is suited for residential and light commercial HVAC air handling units, industrial blowers, and belt-driven equipment requiring a compact, single-groove drive pulley. The QD bushing system allows the sheave to be mounted and removed without special tools, making it well suited for installations where routine belt service or component replacement is expected. Its iron construction offers the durability needed for continuous-duty rotating equipment in mechanical rooms and equipment yards.
