About Two-Piece Clamp-On Shaft Collars

You can install or remove these two-piece clamp-on shaft collars, also known as double-split shaft collars, without removing other parts on the shaft, which helps reduce downtime in maintenance and repair tasks. They can be installed anywhere on the shaft and don't require you to disassemble the machine if you don't have access to the ends of the shaft. Set screws are not required to hold the clamp in place, making these shaft collars less likely to damage the shaft than set-screw shaft collars. The clamp-on design evenly distributes the gripping force around the shaft for a more secure hold than set-screw collars and makes it easier to fine-tune the shaft collar's position.

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.
