CONSTRUCTED AS CURVED BEAMS OF UNIFORM STRENGTH, THE RADIAL WIDTH IS REDUCED TOWARDS THE FREE ENDS SO THAT A CONSTANTLY ROUND SHAP IS MAINTAINED THROUGHOUT CONTINUOUS USE. THIS FORM OF CIRCLIP OFTEN USED IN ASSEMBLIES SUBJECTED TO STRONG CENTRIFUGAL FORCES, IS ALSO SECURE AGAINST HIGH ROTATIONAL SPEEDS. LUGS WITH HOLES ARE PROVIDED FOR RAPID FITTING OR REMOVAL WITH CIRCLIP PLIERS.
