Browning 1010628 3B62Q Qd Bushed V Belt Sheave 3 Groove

Product Description

The BROWNING 1010628 is a QD bushed V belt sheave, sold under the manufacturer designation 3B62Q. It features three grooves and accepts Q1-style quick-detach bushings, allowing straightforward installation and removal without special tooling. The outside diameter measures 6.55 inches, with a belt pitch A diameter of 5.8 inches and a belt pitch B diameter of 6.2 inches. Bore diameter is adjustable from 3/4 inch to 2-11/16 inch depending on the bushing selected. Cast iron construction makes it suited to the load and speed demands of industrial and commercial mechanical drive systems. HVAC technicians and millwrights are the typical installers for sheave-and-belt drive assemblies on fan and blower applications.

This sheave is used in belt-driven fan, blower, and pump applications found in commercial and industrial HVAC systems, as well as general mechanical power transmission setups. The three-groove design supports multiple V belt configurations, distributing load across parallel belts to handle higher torque requirements. Compatible belt trade sizes include A, B, and 5V profiles. The Q1 QD bushing mount makes this sheave adaptable to a range of shaft diameters within the stated bore range, reducing the need to stock multiple fixed-bore sheaves for different shaft sizes.

Designed for use with Q1-style QD bushings and compatible with A, B, and 5V V belt trade sizes. Suitable as a replacement or new-installation sheave in belt-driven HVAC fan and blower systems requiring a 3-groove, 6.55-inch OD sheave with QD bushing mount.

Installation Notes

Installation should be performed by a qualified mechanic or HVAC technician. Disconnect and lock out all power to the drive system before handling the sheave or bushing. Ensure the selected QD bushing matches the shaft diameter before assembly, and verify belt tension and sheave alignment after installation per standard mechanical drive practices. Do not operate the drive without all belt guards and safety covers in place.
