Description

JAx12mm QD® Style Bushing, 12mm Bore, Steel

The JAx12mm is a JA series QD style bushing with a 12mm bore, machined from solid steel with a black oxide finish. It mounts any JA-bushed component, including sheaves, sprockets, and timing pulleys, to a 12mm 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.

$50 minimum order on drive components. Mix and match any pulleys, bushings, sheaves, sprockets, and accessories in your cart to reach the $50 minimum. Questions? Call (888) 203-2358.

Frequently Asked Questions

What does the JAx12mm bushing fit?

It fits any sheave, sprocket, pulley, or coupling machined for a JA series QD style bushing, and mounts that component to a 12mm shaft. The JA size is standardized across manufacturers, so the component brand does not matter.

Does the JAx12mm replace the Dodge JA x 12MM bushing?

Yes. The JA series dimensions are an industry standard, and published interchange data crosses the JAx12mm directly to the Dodge JA x 12MM, as well as Martin JA 12MM, Gates JA 12MM, Optibelt JA12. 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.
