Description
SFx1-1/4 QD® Style Bushing, 1-1/4 in Bore, Steel
The SFx1-1/4 is a SF series QD style bushing with a 1-1/4 in bore, machined from solid steel with a black oxide finish. It mounts any SF-bushed component, including sheaves, sprockets, and timing pulleys, to a 1-1/4 in 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 SFx1-1/4 bushing fit?
It fits any sheave, sprocket, pulley, or coupling machined for a SF series QD style bushing, and mounts that component to a 1-1/4 in shaft. The SF size is standardized across manufacturers, so the component brand does not matter.
Does the SFx1-1/4 replace the Dodge SF X 1-1/4 bushing?
Yes. The SF series dimensions are an industry standard, and published interchange data crosses the SFx1-1/4 directly to the Dodge SF X 1-1/4, as well as Martin SF 1 1/4, Gates SF 1.1/4, TB Woods SF114. 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.
Does the SFx1-1/4 ship from Houston?
Yes. Stock items ship same day from our Houston, Texas warehouse. Call (888) 203-2358 to confirm availability.
