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.

Application of Taper Lock Bushings

Taper-Lock bushings are an excellent choice for installing pulleys on shafts. Unlike flanged bushings, tapered locking bushings have a smaller load center, so you don’t need to worry about them being too tight. Due to their taper, they also help stabilize overhanging loads. Cone lock sprockets are available in a variety of sizes .
Keyless shaft locking allows more torque transfer for a given diameter shaft. They will also keep the stress evenly distributed across the outside and inside diameters of the shaft, rather than concentrating it in the keyway. They can also cause thin hubs to crack under high pressure. Therefore, you should look for shafting made of walls of minimum thickness. When purchasing a locking bushing, make sure the wall thickness of the shaft is appropriate for the type of application you have in mind.
Keyless shaft-to-hub locking devices are another common type.

They allow for easy removal and repositioning of components while eliminating gaps and synchronization issues. They also do not require threads, which makes them more economical and popular for low-volume applications. Additionally, they are easier to install and do not require the milling of keyways. As an added bonus, keyless bushings are less expensive and allow for higher shaft tolerances, making them an excellent choice for a variety of applications.
Keyless shaft-to-hub locking devices work by compressing an inner sleeve with a tapered outer and inner diameter. The inner sleeve is installed on the shaft and in the hub hole of the assembly. By tightening the bolts in the locking mechanism, the inner sleeve squeezes and compresses the shaft within the outer diameter of the hub. This ensures a secure connection.
