Nx80mm QD® Style Bushing, 80mm Bore, Ductile iron (65-45-12)

The Nx80mm is a N series QD style bushing with a 80mm bore, machined from solid ductile iron (65-45-12). It mounts any N-bushed component, including sheaves, sprockets, and timing pulleys, to a 80mm shaft. Every bushing is machined from solid stock, never sintered or powdered metal, which matters in a part that transmits its load through a friction fit.

Frequently Asked Questions

What does the Nx80mm bushing fit?

It fits any sheave, sprocket, pulley, or coupling machined for a N series QD style bushing, and mounts that component to a 80mm shaft. The N size is standardized across manufacturers, so the component brand does not matter.

Does the Nx80mm replace the Dodge N X 80MM bushing?

Yes. The N series dimensions are an industry standard, and published interchange data crosses the Nx80mm directly to the Dodge N X 80MM, as well as Gates N 80MM, Optibelt N80. Verify bore size before ordering.

How does a QD style bushing install?

QD style bushings are flanged and split through the flange and barrel. Slide the bushing onto the shaft, seat the component on the taper, and tighten the cap screws through the flange into the component. Torquing the screws compresses the split barrel onto the shaft. Reverse the screws into the jacking holes to remove.
