Description

R1x2-3/8 Split Taper Bushing, 2-3/8 in Bore, Steel

The R1x2-3/8 is a R1 series split taper bushing with a 2-3/8 in bore, machined from solid steel with a black oxide finish. It mounts any R1-bushed component, including sheaves, sprockets, and timing pulleys, to a 2-3/8 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 R1x2-3/8 bushing fit?

It fits any sheave, sprocket, pulley, or coupling machined for a R1 series split taper bushing, and mounts that component to a 2-3/8 in shaft. The R1 size is standardized across manufacturers, so the component brand does not matter.

Does the R1x2-3/8 replace the Dodge R1 X 2-3/8 bushing?

Yes. The R1 series dimensions are an industry standard, and published interchange data crosses the R1x2-3/8 directly to the Dodge R1 X 2-3/8, as well as Martin R1 2 3/8, US Tsubaki R1-2F, Regal Rexnord (Browning) R1 2 3/8. 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.
