Bolt-on hubs provide a rigid, secure connection between a shaft and a rotating component such as a sheave, sprocket, or coupling. The B15 features a 1-1/2 inch bore and is built to handle the demands of industrial and commercial equipment service. Licensed technicians and mechanical contractors working on HVAC blower assemblies, fan drives, and similar rotating equipment will find this hub a direct-fit replacement solution where a bolt-on style mount is specified.

The MIDWEST TOOL B15 bolt-on hub is suited for use in residential and commercial mechanical systems where shaft-to-component connections require a positive-locking, bolt-on configuration. Typical applications include blower wheel hubs, fan drive assemblies, and belt-drive components in HVAC and light industrial equipment. Installation is performed by mechanical and HVAC service technicians during equipment overhaul, blower assembly replacement, or drive component upgrade work.
