Midwest Tool B20 2 Inch Bolt-on Hub

Product Description

The MIDWEST TOOL B20 is a 2-inch bolt-on hub designed for secure mechanical shaft attachment in trade and industrial applications. Bolt-on hubs provide a reliable, removable connection between a shaft and a rotating component such as a pulley, sprocket, or wheel. The B20 is installed directly onto a shaft using bolts, eliminating the need for keyways or set screws in applications where they are not practical. Weighing 2 pounds and measuring 9.75 inches by 4 inches by 3.75 inches, this hub is sized for straightforward handling and installation by mechanical, HVAC, or industrial service technicians.

The B20 bolt-on hub suits residential and light commercial mechanical systems where positive shaft engagement is required. Typical applications include fan assemblies, blower systems, conveyor drives, and similar rotating equipment. It is suited for installations where the hub must be periodically removed for maintenance or component replacement without damaging the shaft surface.
