Browning 3693827 Qd Bushed V Belt Sheave 1 Groove

Product Description

The BROWNING 3693827 is a single-groove, QD bushed V-belt sheave designed for power transmission applications in HVAC, industrial, and mechanical systems. The sheave accepts a Quick Detach (QD) bushing style B, allowing fast installation and removal without specialized tooling. The outside diameter measures 16.28 inches, with a 5V belt pitch diameter of 16.1 inches and a B-belt pitch diameter of 16.0 inches. Bore diameter ranges from 5/8 inch minimum to 2-1/4 inch maximum, giving installers flexibility across a range of shaft sizes. At 17.85 pounds, this is a heavy-duty cast component built for continuous drive service.

This sheave is suited for single-groove V-belt drive systems found in commercial and industrial HVAC air handlers, fans, blowers, and general mechanical power transmission setups. The QD bushing design makes it practical for both new installations and retrofit work where the drive assembly needs to be reconfigured or serviced in the field. HVAC mechanics and millwrights are the primary installers for components of this type.

Installation Notes

Installation should be performed by a qualified HVAC technician or millwright. Disconnect and lock out all power to the drive system before removing or installing sheaves. The QD bushing must be properly torqued per bushing manufacturer guidelines and seated flush before re-energizing the drive. Verify belt alignment with a straightedge or laser alignment tool after installation to prevent premature belt and bearing wear.
