Tsubaki offers the most complete line of “QD ® ” Style weld-on hubs for insertion and welding to produce “B” style sprockets, sheaves, and other applications. 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 (not powdered or sintered metal). The “QD ® ” Style Weld-On hubs listed below include appropriate tapered bores and mounting holes. QD ® Weld-On hubs are manufactured with a step for assistance in locating the attached plate. This is shown as the “T” dimension and depending on the width of the plate, the result is either a B-style or C-style sprocket.
