3020 Taper Lock Bushings

Tapered locking bushings are designed to mechanically connect two or more shafts and have tapered surfaces. They provide flexibility between primary and secondary components and feature ISO-compliant threads and keyways. QTL tapered bushings are mounted on tapered hubs and QTL tapered bushings are mounted on keyways. Both styles are machined to ISO standards.
The dimensions of the tapered locking bushing are defined by four digits, including the flange. The first two digits of the size represent the maximum bore diameter and the last two digits are the length of the bushing. For example, a 1.5" diameter tapered locking bushing is 1-1/2". Similarly, metric bore diameters are given by placing "MM" after the metric dimension. Additionally, the tapered locking bushings are flush with the tapered pulleys and sprockets.

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.

How to Choose a Taper Lock Bushing

If you are replacing a transmission bushing, you will need to use a tapered lock bushing. The parts are simple but should be installed correctly. To ensure proper functionality, follow the instructions carefully. Otherwise, you may damage the bushing and void any manufacturer's warranty. The size chart below can help you choose the right bushing for your needs. Use it as a guide when ordering.
The diameter of the shaft bore and its length determines the size of the Taper-Lock bushing. The taper reduces the length of the through-hole and allows the bushing to fit better than flanged bushings. The taper is 8 degrees long, so a 1.5" diameter taper is 1-1/2" long. For metric applications, the metric designation is "MM". Taper locking bushings are flush with sprockets or pulleys.
The Taper-Lock bushing system allows the sprocket hub to be smaller than ever. The through-hole length dimension has been reduced by approximately 3%, and the shaft can be mounted close to the bearing without any problems. These bushings feature tapered handles with wedge action, making them easy to install and remove without deforming the shaft. These bushings come in different sizes and styles.
