Spiral retaining rings, also known as spiral rings, are axial fastening elements designed to fit into machined grooves on shafts or in housings in order to retain components and prevent axial movement. Unlike conventional circlips (DIN 471 or DIN 472 types), spiral retaining rings have no ends with assembly holes, they are formed from a flat strip wound helically that fits the groove perfectly.They can be manufactured as single-turn or multi-turn rings, which increases their load capacity and stability. They are normally produced in carbon spring steel, stainless steel or special materials for applications requiring resistance to corrosion or extreme temperatures.
Spiral retaining rings are used in aerospace, automotive, industrial machinery, medical equipment, transmission systems, bearings and precision applications, where reliability, mechanical strength and a good surface finish are key requirements.
To guarantee optimum performance it is essential to select the spiral type, the material and the number of turns to suit the load and the working environment, which allows us to meet the specific requirements of each customer and sector. We hold standard solutions in stock and also offer made-to-measure manufacture, always guaranteeing the quality, traceability and international compatibility that characterise every OSN product.
