3030 Taper Lock Bushings

Split Taper Bushings, also known as QDs, are designed to mount pulleys and sprockets to shafts. They are separated along their outer diameter and keyed to the drive components, ensuring that the components are securely mounted on the shaft even if the fasteners break. Split tapered bushings are interchangeable between manufacturers, so you don't have to worry about figuring out what kind of bushing you need based on its appearance.
A tapered bushing is a locking mechanism commonly used in power transmission components. They are made of precision cast iron and computer etched to specify their dimensions. These bushings feature wedge action handles for a secure connection and excellent clamping force. The most common types of tapered bushings are QD bushings and Taper-Lock bushings. Typically, they are used in applications requiring high torque.
Another tapered bushing is the QTL Tapered Lock Clamp Bushing. These bushings are designed to clamp the hub securely to the axle. They provide greater alignment and are more accurate than keyways. To install a taper lock bushing, you must order the appropriate QTL taper lock flange and hub. This ensures a tight fit. This is comparable to a shrink-fit because the two bushings do not move once installed.

安装

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.

搬迁

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.

Tips for installing taper lock bushings

This type of bushing is flush with the shaft of the tapered pulley or sprocket. There are some tips for installing these bushings. First, make sure the assembly has the correct shaft hole size.
Tapered bushings are often used on shafts to mount pulleys or other rotating parts. They have a split flange, which is screwed on. They provide strong clamping force, making them an excellent choice for high torque applications. If you want to make sure the tapered bushing is the correct size, look for the wedge action type. The wedge action design helps lock the bushing without deforming the shaft and is easy to remove if necessary. You can find several different types of tapered bushings, including QD and Taper-Lock.
Split tapered bushings are commonly used to mount sprockets or pulleys to shafts. They are designed to withstand the torques experienced during power transmission. They are made of double-section steel and flanged designs. They are usually interchangeable between manufacturers. If you can't find what you're looking for in the catalog, you can always use a third-party tapered bushing.
