Steel Taper Bore Weld-on Hubs are drilled, tapped and bored to receive standard taper bushings. The extended flange provides a convenient means for welding devices, which must be firmly fastened to a shaft.
Type W
The ‘W’ Type Weld-on-Hub is designed for applications with a relatively high demand torque. The taper bore has a recess machined in the centre to prevent distortion of the taper when a heavy weld bead is applied.

Type WH
The ‘WH” Type Weld-on-Hub is designed for applications with a relatively low torque, requiring only moderate weld strength. A heavy run of weld on the WH hub may cause some distortion of the taper bore.
