Introduction to Internal Circlips
Internal circlips, also known as retaining rings, are a type of fastener used to hold components in place within a bore. They are typically made of spring steel and have a circular shape with a gap in the circumference. This gap allows the circlip to be installed into the bore by compressing it radially, and then it expands to fit into a groove in the bore, providing a secure retaining force. Internal circlips are widely used in various industries such as automotive, machinery, aerospace, and electronics to prevent axial movement of components. Internal Circlips
