Constant Section Retaining Rings are manufactured by coiling heavy section wire. This process yields a retaining ring that supports high thrust loads. Plier type tools are available to ease installation on some series of rings. Many material and finish choices are available and custom designs typically do not require any custom tooling, so specials are very economical to produce.
