一个 External Spiral Retaining Ring is a circular fastening component that is intended to be inserted into a groove on the exterior of a rod or part. It’s a consistent design that offers a full 360 degree of contact, it distributes uniform loads across the surface without the presence of ears or extra features. External spiral bands are commonly employed to bind together bearings, gears, pulleys, and other components that are mounted to the shaft. This offers superior stability and resistance to vibrations compared to traditional bands.
