External Spiral Rings

An external spiral ring, also known as an external spiral retaining ring or external spiral snap ring, is a type of fastener used to retain components on the outside of a shaft or in a groove with a spiral or coiled design. These rings are similar in function to other retaining rings but have an outward-facing spiral shape. External spiral rings are typically made of spring steel and have a continuous coil that can expand or contract to fit around the outside of a shaft or within a groove. When installed, they exert radial pressure against the groove's walls or the shaft's surface, effectively securing the components in place. This spiral design allows for flexibility and self-adjustment, making them suitable for applications with varying shaft diameters. These rings find use in various industries, including automotive, aerospace, and manufacturing, where they are used to secure components like bearings, wheels, or gears onto shafts or in grooves. In summary, external spiral rings are innovative fasteners designed for reliable component retention in situations where adaptability and flexibility are required due to variations in shaft diameter or other factors.
