Internal Retaining Ring

An internal retaining ring, also known as an internal retaining clip or internal snap ring, is a type of fastener used to secure components within a bore or a cylindrical recess. Unlike external retaining rings that fit around the outside of a shaft, internal retaining rings are installed on the inside of a bore or groove. These rings typically have a circular or semi-circular shape with open ends and are designed to fit into a groove or recess within a housing or on the inside of a cylindrical component. When installed, they exert radial pressure against the walls of the bore or recess, preventing the assembly from moving or coming apart. Internal retaining rings are commonly used in various applications, including automotive, machinery, and industrial equipment, to secure bearings, shafts, gears, and other components inside housings or bores. They come in different sizes, materials (such as steel or stainless steel), and configurations to accommodate specific bore diameters and application requirements. In summary, internal retaining rings are essential fasteners that help maintain the positioning and integrity of components within a cylindrical bore or recess.
