Description
S1x3-5/8 Split Taper Bushing, 3-5/8 in Bore, Steel
The S1x3-5/8 is a S1 series split taper bushing with a 3-5/8 in bore, machined from solid steel with a black oxide finish. It mounts any S1-bushed component, including sheaves, sprockets, and timing pulleys, to a 3-5/8 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.

Frequently Asked Questions
What does the S1x3-5/8 bushing fit?
It fits any sheave, sprocket, pulley, or coupling machined for a S1 series split taper bushing, and mounts that component to a 3-5/8 in shaft. The S1 size is standardized across manufacturers, so the component brand does not matter.
Does the S1x3-5/8 replace the Dodge S1 X 3-5/8 bushing?
Yes. The S1 series dimensions are an industry standard, and published interchange data crosses the S1x3-5/8 directly to the Dodge S1 X 3-5/8, as well as Martin S1 3 5/8, US Tsubaki S1-3J, Regal Rexnord (Browning) S1 3 5/8. Verify bore size before ordering.
How does a split taper bushing install?
Split taper bushings are split through both the barrel and the taper, with a keyed barrel. Slide the bushing onto the shaft, seat the component, and tighten the cap screws. The double split gives high clamping force on the shaft without scoring it. Reverse the screws into the jacking holes to remove.
Does the S1x3-5/8 ship from Houston?
Yes. Stock items ship same day from our Houston, Texas warehouse. Call (888) 203-2358 to confirm availability.
