Shaft collars hold and position mechanical components around a shaft or mount shafts, tubes, and pipes onto flat surfaces, Available in a variety of styles and from numerous material types, shaft collar selection depends heavily on the details of the intended application.

HOW A SHAFT COLLAR WORKS
Commonly found in power transmission applications, shaft collars are ring-shaped plastic or metal devices that clamp around a shaft. The purpose of the collar is usually to hold motor components, gear assemblies, sprockets, bearings, and other parts in place and sometimes facilitate their proper movement. The collars may specifically locate components, keep them appropriately spaced, or limit their movement. Shaft collars may also be used to connect one end of the shaft itself to a part or surface.
The simplest shaft collars use set screws that tighten into the shaft to hold the collar in place. While these collars still see some use, the screws tend to mar the shaft which makes it difficult to remove and reposition the collars. Most modern shaft collars use a clamp that holds to the shaft. Clamp screws tighten the clamp around the shaft without the need to dig into the shaft itself.
There are multiple types of shaft collars, each suited to different purposes. Some of the most common types of shaft collars include:
Hinge shaft collars have an open hinge on one side and a clamp screw on the other, enabling them to be easily assembled anywhere on the shaft. They are completely self-contained and eliminate the risk of dropping or losing screws.
One-piece shaft collars feature improved performance, allowing an easy increase in clamping force by tightening the clamp screw.
Two-piece shaft collars can be assembled anywhere on the shaft, including between other shaft collars.
Shaft collars are also available in multiple bore configurations, including round, threaded, hexagonal, and square. While off-the-shelf shaft collars are suitable for many needs, standard shaft collars can be altered to meet specific application needs. Fully customized shaft collars are also an option for unique situations.
