DIN Standard External Snap Ring

Snap rings, also referred to as spiral rings, are versatile fasteners commonly used in various applications where components need to be securely retained within a cylindrical bore or housing with grooves. These rings are designed to provide constant radial force by sitting tightly within the circular component, acting as a spring that pushes outward against the bore walls. External snap rings, a specific type of snap ring, are installed into grooves or recesses on the external diameter of shafts or cylindrical components. Unlike internal snap rings, external snap rings do not have lugs or tabs protruding outward, which can interfere with the assembly process. This design feature allows for smooth and uninterrupted assembly operations. External snap rings are commonly used in applications where components need to be securely retained on the outside diameter of shafts or cylindrical components. They provide reliable retention while allowing for easy installation and removal when necessary.
