2525 Taper Lock Bushings

Whether installing tapered lock bushings or replacing old ones, you need to understand what those bushings are and what you're dealing with. These bushings are designed to connect significant components through their tapered surfaces, and they incorporate keyways or threads in their design. These bushings are machined to ISO standards, and you will find them mounted on tapered hubs in tapered bearings.
The Taper-Lock bushing is named for its 8-degree taper, making it much shorter than its planned counterpart. The bushing is mounted with a blind hex socket head cap screw that compresses the inner diameter of the bushing to fit the key shaft. You will find tapered bushings available in various post bore diameters, so you need to know your specific needs before purchasing. Be sure to follow the instructions carefully to install the tapered bushing properly.

Installation

1. Clean all oil, dirt, and paint from the shaft, bushing holes, bushing exterior, and bores of components (sprockets, pulleys, etc.).
2. Insert the bushing into the assembly. Match hole patterns, not threaded holes (each hole is threaded on one side only).
3. Thread the set screw or cap screw into the half-threaded hole shown below. Install the assembly on the shaft.
4. Alternately set the torque setting or cap screw* to the recommended torque setting in the table below.
5. Fill all unoccupied holes with grease.

Removal

1. Remove any retaining or cap screws.
2. Insert the set screw or cap screw into the above hole.
3. To reinstall, complete all five (5) installation instructions.

There are several reasons for choosing a tapered locking bushing, but perhaps none is more critical than preventing leaks. This unique feature can be used in a variety of applications including pulleys, and sprockets. If you're wondering if you should buy this type of bushing for your specific application, keep reading. We will explain them one by one.
Another important feature of tapered locking bushings is their precision tolerances. They are commonly used in power transmission applications, including power transmission and distribution. And because they're made with cap screws, they're safer than traditional bushings. In fact, most tapers are SAE Class 5 tolerances, making them ideal for a variety of industries. Here are some other benefits of tapered locking bushings:
The split cone bushing contains a split barrel. Because they're split, they don't need to fit a hole perfectly, and they're versatile enough to accommodate changing shaft sizes. They are also very easy to install, making them an excellent choice for applications that require precision. While these types of bushings are expensive, the extra safety they provide is worth it. They are more durable than traditional bushings and keep your transmission and other components from slipping.
