Built from iron, this sheave accepts both A and B series V-belts, with a belt pitch diameter of 10.5 inches for A-series and 10.9 inches for B-series. The outside diameter measures 11.25 inches. The QD (Quick Detachable) bushing design allows for straightforward installation and removal without special tooling. Bore diameter is field-selectable from 0.375 inches up to 1.5 inches using the appropriate H-style QD bushing, sold separately. This sheave is a standard choice for HVAC equipment, fans, blowers, and general power-transmission applications.

This sheave is suited for residential and commercial HVAC systems, ventilation fans, industrial blowers, and other belt-driven rotating equipment that calls for a single-groove A or B series drive. The H-style QD bushing interface is a common standard in the trade, making this sheave a practical drop-in option during equipment replacement or drive upgrades. The 11.25-inch outside diameter and broad bore range make it adaptable to a wide range of shaft sizes encountered in the field.

Installation Notes

Installation should be performed by a qualified HVAC technician or millwright. Disconnect and lock out all power to the drive system before beginning work.

Verify sheave alignment with a straightedge or laser alignment tool after mounting to prevent premature belt and bearing wear.
