Internal Lugs

Internal lugs, a specific feature of certain types of internal circlips or retaining rings, are designed to be inverted to fit into the bottom of a groove within a cylindrical bore or housing. These inverted lugs offer several advantages, including providing greater clearance on a shaft or within a housing. The inverted design of internal lugs allows them to sit flush with the bottom of the groove, maximizing available space on the shaft or within the housing. This feature is particularly beneficial when retaining bearings or other components with large corner radii or chamfers, as it ensures optimal clearance without interference. Furthermore, internal lugs often feature grip holes, which allow for quick and easy installation or removal of the circlip using circlip pliers or similar tools. This facilitates efficient assembly and maintenance tasks, reducing downtime and enhancing productivity.
