Description
SKx42mm QD® Style Bushing, 42mm Bore, Steel
The SKx42mm is a SK series QD style bushing with a 42mm bore, machined from solid steel with a black oxide finish. It mounts any SK-bushed component, including sheaves, sprockets, and timing pulleys, to a 42mm 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 SKx42mm bushing fit?
It fits any sheave, sprocket, pulley, or coupling machined for a SK series QD style bushing, and mounts that component to a 42mm shaft. The SK size is standardized across manufacturers, so the component brand does not matter.
Does the SKx42mm replace the Dodge SK X 42MM bushing?
Yes. The SK series dimensions are an industry standard, and published interchange data crosses the SKx42mm directly to the Dodge SK X 42MM, as well as Martin SK 42MM, Gates SK 42MM, TB Woods SK42MM. 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 SKx42mm ship from Houston?
Yes. Stock items ship same day from our Houston, Texas warehouse. Call (888) 203-2358 to confirm availability.
