Shaft Collars for Precision Applications

The shaft collar is commonly used in machine applications to hold different mechanical components in place. Shaft collars are made up of a round metal or plastic ring with a clamp and/or screws to tighten the ring around a component to hold it in place. Shaft collar designs are tailored to different shapes, sizes, and strengths to best support a given mechanical application.
