Product Description

The BROWNING 1010404 is a three-groove, QD-bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical drive systems. It accepts a Q1-style quick-detach bushing, which allows for fast installation and removal without specialized tooling. The outside diameter measures 5.75 inches, with a Belt Pitch A diameter of 5.0 inches and a Belt Pitch B diameter of 5.4 inches. Bore range spans 0.75 inches minimum to 2.6875 inches maximum, accommodating a wide variety of shaft sizes. At 8.25 pounds, this sheave is built for durability in continuous-duty drive configurations. Installation is typically performed by licensed HVAC technicians and millwrights.

This sheave is suited for use in belt-driven blower assemblies, fan drives, and general mechanical power transmission setups found in commercial and residential HVAC equipment as well as light industrial machinery. The three-groove design allows it to run multiple V-belts simultaneously, distributing load and improving drive reliability. It is commonly paired with A-section or B-section V-belts depending on the selected groove profile.
