Set-Screw Shaft Collars

Set-Screw Shaft Collars

The most commonly used style of shaft collar, set-screw shaft collars slide onto a shaft and are held in place with a set screw, which is tightened until it bites into the shaft material. For best results when installing these shaft collars, select a shaft collar that has a set screw made from a material that is harder than the shaft material. You may have to remove other components on the shaft before installing or removing the shaft collar.

General Purpose Steel

Steel shaft collars provide good strength and hardness and are the most common choice for a wide range of applications where corrosion is not a concern.

Washdown Acetal

Ideal for applications where equipment will be washed down frequently, such as food-and-beverage processing equipment, acetal shaft collars will not rust or corrode when exposed to water. They are nonmagnetic.
