Made-to-Order Sprockets - Tsubaki

“QD” Style Weld-On HubsTsubaki offers the most complete line of “QD” Style weld-on hubs for insertion and welding to produce “B” style sprockets, sheaves andother applications without hub protrusion. To provide greater strength for this type of shaft locking mechanism and reduce heat distortioncaused by welding, these hubs are dimensionally the same as our sprocket items. Special dimensional hubs are available per yourspecifications on a made-to-order basis. All Tsubaki hubs are made from steel bar stock (not powdered or sintered metal). The “QD” Styleweld-on hubs listed below include appropriate tapered bores and mounting holes.All dimensions in inches unless otherwise stated.Catalogue Bushing Max.
