R2 Split Taper Bushings

Taper bushings are used in many applications but are most commonly used as power transmission components. They attach shafts to rollers or pulleys and feature a wedge-shaped design for quick and easy installation and removal. Some common types of tapered bushings are QD and Taper-Lock. The tapered sleeve is an important part of the power transmission device. It’s precision cast iron construction is ideal for high-speed applications and is computer etched for sizing. High-strength screws are used to tighten the tapered part of the assembly. These bushings ensure that the sprockets are properly installed and aligned. They are also popular in recessed ceiling lights. They also provide great clamping force.

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.

Application of taper bushings

To ensure optimum performance of the taper, you need to know how to properly apply the taper bushing. In this article, we’ll explore some common applications for tapered bushings. We’ll also discuss how to use different types of tapered bushings to prevent misalignment and maximize your torque. Here are some tips to help you maximize the benefits of taper.
When choosing a tapered bushing, make sure the diameter of the shaft is correct. Tapered Locking Bushings feature an 8-degree taper to reduce through-hole length. The bushing is held in place by screws. It is important to clean the bushing thoroughly before use to ensure proper installation. Otherwise, grease and oil may cause the bushing to break or be installed too deep.
The main purpose of the tapered bushing is to lock the shaft and other components together. In power transmission applications, tapered bushings are used to connect shafts to rollers and pulleys. Designed to provide a firm grip and high torque, these bushings are useful in many different situations. A popular application is the recessed installation of ceiling lights. They are also effective in high torque applications due to their even installation.
