R1 Split Taper Bushings

If you’re in the market for a new bushing for your vehicle, you’ve probably come across the R-Type Split Taper Bushing. These are ideal for applications where torque, weight, and axial force are critical. Both sections of the SH bushing are threaded to match the taper angle. When tightened, the outer component climbs up the threads of the inner bushing, resting it against the shaft or hub. These bushings eliminate the need to machine keyways or increase the diameter of the shaft and hub. They also eliminate the need for axially fixed joints.

1. Make sure the bushing cone and interior of the driven product are clean and free of anti-seize lubricant.
2. Place the bushing into the sprocket or other part type that accepts bushings.
3. Loosely place the cap screws into the pull-up holes. The bushing remains loose to ensure a slip fit on the shaft.
4. Using the key on the shaft, slide the sprocket or other part type to the desired position on the shaft. Make sure the heads of the cap screws are accessible.
5. Align the sprockets or part types, alternately and incrementally tighten the screws until they are taut. Do not use extensions on the wrench handle, and do not allow sprockets or parts to be pulled out and contact the bushing flange. There should be a gap between the bushing flange and the sprocket at this point to ensure that the gap does not close.


1. Loosen and remove cap screws.
2. Insert the cap screws into the threaded removal holes.
3. Tighten the inserted screws until the sprocket or other part type is loose on the shaft.
4. Remove sprocket/part type from the shaft.

Tips for Installing R1 Split Taper Bushings

For transmission components, the R1 split taper sleeve is essential. Made from tough malleable iron, these bushings have 2 indestructible keys designed for maximum torque and a true concentric grip. In addition to being widely used in transmission components, these bushings are also available in a variety of sizes to suit a variety of applications. Read on for some tips on installation.
First, make sure the bushing is free of any anti-seize lubricant. Next, insert them into the appropriate parts, such as sprockets. Make sure the bushing slides onto the shaft without resistance, then secure it with the cap screw. When installing a new bushing, loosen it so that it does not interfere with the sprocket key.
