Browning 1001551 2 Groove Qd V Belt Sheave 4.95 in Od

Product Description

The BROWNING 1001551 is a two-groove, QD bushed V-belt sheave designed for use in belt-driven power transmission systems common to HVAC, industrial fan, and blower applications. It accepts a P1-style Quick Detachable bushing, allowing fast installation and removal without specialized tooling. The outside diameter measures 4.95 inches, and the bore diameter range spans 0.5 to 1.75 inches, providing flexibility across a range of shaft sizes. With a belt pitch A diameter of 4.2 inches and a belt pitch B diameter of 4.6 inches, the sheave is compatible with standard A and B cross-section V-belts. It weighs 4.9 pounds and is built for reliable torque transfer in rotating equipment assemblies.

This sheave is suited for residential and light commercial HVAC equipment, including belt-drive air handlers, blowers, and fans where a two-groove drive configuration is required. It is also applicable in general industrial power transmission setups. The QD bushing system makes it a practical choice for installations where shaft alignment and periodic belt service are routine maintenance tasks. Licensed HVAC technicians and mechanical contractors are the primary installers of this component in field service and new equipment installation scenarios.

Installation Notes

Installation and removal should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out all power to the drive system before servicing the sheave or belts. The P1 QD bushing must be seated and torqued according to the bushing manufacturer's specifications before returning the drive to service. Verify belt tension and sheave alignment after installation to prevent premature wear.
