Tsubaki offers a complete line ofSplit Taper style 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 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 Tsubaki hubs are made from steel bar stock (notmore powdered or sintered metal).
The Split Taper style weld-on hubs listed below include appropriate tapered bores and mounting holes.
