Medium heavy duty external spiral retaining ring carbon steel, plain. Spiral retaining rings are axially installed into housings/bores (internal) or onto shafts (external), making 360° contact with the groove. Spiral retaining rings have no ears or lugs to interfere with the assembly. These rings are manufactured by coiling flat wire into the shape of the finished retaining ring. Spiral rings are provided with a removal notch to simplify the removal process. No special tools are required for installation or removal. Spiral retaining rings can be economically produced in special alloys like stainless steel because the manufacturing process eliminates scrap.
