一个 Internal Spiral Retaining Ring is a fastening component that is designed to be inserted into a channel in a housing or bore. Unlike the traditional卡环 design, the spiral design offers a continuous 360-degree contact. This design distributes uniform loads across the ring and has a high degree of stability. Internal spiral bands are commonly employed to bind together bearings, gears, sleeves, and other components located in bores. This offers superior retention without additional components or vibrations and minimizes movement or vibration.
