P2 Split Taper Bushings

There are many different types of tapered bushings, and knowing each can help you get the most out of your part. Here are some things to consider. Read on for more information. Also, know what they are used for. A tapered bushing is used to connect the 2 shafts. Standard tapered bushings have 2 parallel radii, while tapered locking bushings have a four-degree radius.
Conical bushings are used in power transmission applications. They are made of precision cast iron and are usually flangeless. They are separated along the length of the shaft, which allows them to provide excellent clamping force. They are also common in recessed ceiling lights. Their uniform mounting means they are very effective in high torque applications. To learn more, read on to learn more about these popular bushings.
One of the most common types is split tapered bushing. Bushings of this type are used to mount sprockets, pulleys, and pulleys on shafts. The barrel of the split tapered bushing is split at 2 points so even when the fasteners are loose, the inner diameter compresses and holds the drive part on the shaft. Split tapered bushings are interchangeable between manufacturers.

Advantages of Split Taper Bushings

Split tapered bushings offer several advantages over straight bore pulleys. For starters, the split bushing fits snugly against the shaft rather than sticking out of the center. Straight bore pulleys tend to wear shafts of different diameters and can also corrode. Even 4 inches from the center of the pulley, the difference in shaft diameter is significant.
Split tapered bushings are similar to QD bushings, but the barrel is split into 2 places before reaching the hub. This means that the fastener needs to be inserted through the flange rather than through the barrel. These bushings are installed on the shaft in 2 different ways, the standard installation requires fasteners to pass through the flange, and the reverse installation requires fasteners to be inserted into the drive part. However, QD bushing systems are prone to OD slippage when fasteners are loose or the barrel is too long. Additionally, split tapered bushings are often interchangeable between manufacturers, making them the OEM’s first choice.


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 keys on the shaft, slide the sprocket or other part type to the desired position on the shaft. Make sure that 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.
