Description

Ex75mm QD® Style Bushing, 75mm Bore, Steel

The Ex75mm is a E series QD style bushing with a 75mm bore, machined from solid steel with a black oxide finish. It mounts any E-bushed component, including sheaves, sprockets, and timing pulleys, to a 75mm 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 Ex75mm bushing fit?

It fits any sheave, sprocket, pulley, or coupling machined for a E series QD style bushing, and mounts that component to a 75mm shaft. The E size is standardized across manufacturers, so the component brand does not matter.

Does the Ex75mm replace the Dodge E X 75MM bushing?

Yes. The E series dimensions are an industry standard, and published interchange data crosses the Ex75mm directly to the Dodge E X 75MM, as well as Martin E 75MM, Gates E 75MM, TB Woods E75MM. 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.
