Crescent Ring

Crescent rings, also known as external crescent rings or external retaining rings, are fasteners designed to be applied outwardly over the shaft. They provide a secure hold against impact and vibration, making them suitable for applications where components need to be retained securely in place. The unique crescent shape of these rings allows them to expand outward when installed over the shaft, exerting pressure against the housing or bore walls. This outward expansion creates a tight and secure fit, preventing the ring from dislodging due to impact or vibration during operation. Crescent rings are commonly used in various industries, including automotive, machinery, and manufacturing, where reliable retention of components is essential for ensuring the integrity and functionality of mechanical assemblies.
