Both Type K and Type W/WA weld-on hubs are made of steel, drilled, tapped and taper bored to receive TAPER bushings. They are very useful for welding into fan ro-tors, pulleys, plate sprockets, impellers, agitators and many other devices which mustbe firmly fastened to the shaft.
Tape K hubs are shorter than Tape W/WA. Both types are rugged in construction.easy to install and are entirely suitable for use where severe operating conditions are en-countered. This construction eliminates mounting difficulties. It also prevents loosening and wear on the hub during operation.
