QD® Weld-on Hubs
Hubs
U.S. Tsubaki offers the most complete line
of QD® and TAPER-LOCK weld-on hubs for
insertion and welding to produce “B” style
sprockets, sheaves, and other applications
without hub protrusion. To provide greater
strength for this type of shaft-locking
mechanism and to reduce heat distortion
caused by welding, these hubs are dimensionally the same as our sprocket items. Special
dimensional hubs are available per your specifications
on a made-to-order basis.
All U.S. Tsubaki hubs are made from steel
bar stock (not powdered or sintered metal).
The QD and TAPER-LOCK weld-on hubs
listed below include appropriate tapered
bores and mounting holes.
