6 WELD-ON-HUBS Fenner Taper Lock Weld-on Hubs are made of steel, grade 070M20, drilled, tapped and taper bored to receive standard Taper Lock bushes. The shouldered outer diameter provides a convenient means of welding hubs into fan rotors, steel pulleys, plate sprockets, impellers, agitators and many other devices which must be firmly fastened to the shaft. *Bore tolerance of D2 +0mm/-0.05mm is recommended Product Code Size UseBush Size D1 D2 * D3 L1 L2 L3 025C0010 WH12

6 holes equally spaced to suit B dia. bolts Welding instructions Fenner Taper Lock Weld-on Hubs are made of steel, are machined to accept Taper Lock bushes for shaft fixing, and have a precision machined shoulder against which flanges or webs can be located. It is recommended that a continuous 45° mitre weld be used, working on the larger hub diameter section only. To ensure accuracy in the welded assembly it is essential to apply only sufficient weld to achieve sufficient strength. Excess weld should not be necessary for normal use and, due to greater heat input, gives a higher risk of distortion. The table below shows recommended continuous fillet weld requirements for each hub size. Hub No Leg Length mm WH12
