E-clips from ITA Fasteners are shaft mounted for rotatory assemblies. They act as the retaining ring in bores and other applications in which radial and centrifugal force is applied to the assembly. The purpose of the e clips is to restrict the loosening of the components due to the rapid rotational motion. They are inserted into grooves placed on shafts to create a shoulder that retains the assembly. These clips eliminate the need for threading, tapping or other machining operations required for traditional fasteners.
The most significant advantage of using these fasteners is the reduction in production cost they bring into the economics of building many assemblies. Ultimately, they provide a functionally superior design compared to the other fasteners. They can quickly be snapped into place using lugs with holes but cannot be fastened and unfastened using traditional tools. Due to their structural built, they cannot be used for lateral movements even within the assembly. It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant.
