Stafford Large Bore Shaft Collars and Rigid Couplings are custom engineered for applications up to 16” and 8” I.D., respectively, and come in one- and two-piece configurations that can be modified to meet a variety of special requirements. Ideal for wind power generator drive systems, they can be precision balanced and incorporate steel targets which can be read from both the face and O.D. to add speed sensing capability to shafts.

Stafford Large Bore Shaft Collars and Rigid Couplings can be machined from aluminum, steel, stainless steels, titanium, brass, and other alloys with dimensional tolerances of <0.001” and run-out and concentricity tolerances of <0.001” TIR, depending upon the part configuration. Modifications can include keyways, slots, cam surfaces, special threads and other features.
