Taperfit or QD weld-on hubs are for use in the fabrication of conveyor pulleys, plate sprockets, fans and impellers. Weld-on hubs are made of low carbon steel for good welding compatibility.

Weld-on hubs are made of 1015-1025 steel, drilled, tapped and taperbored to receive the Taperfit bushing. They are useful for welding into fan rotors, pulleys, plate sprockets, and must be firmly mounted onto shafting. Four types of hubs are available.

QD weld-on hubs: are made of low carbon steel for good welding compatibility. They are useful for welding into fan rotors, impellers and agitators, which require secure mounting to the shaft. A standard type is available in addition to one that is specifically designed for use in the end disc of a conveyor pulley.
