Retaining rings, also known as snap rings or circlips, are mechanical axial fasteners designed to secure components in position within an assembly, preventing their axial displacement on shafts or within housings.

They are installed in machined grooves on a shaft (to limit outward movement) or inside a housing (to limit inward movement), acting as safety shoulders for components such as bearings, gears, bushings, pulleys, or sprockets.

The most common manufacturing materials are spring steel (with heat and surface treatments for enhanced strength) and stainless steel for applications requiring corrosion resistance.

Retaining rings are widely used in automotive engineering, industrial machinery, household appliances, transmissions, hydraulic systems, power tools, and agricultural equipment, thanks to their ease of assembly, low cost, reliability, and resistance to dynamic or vibratory loads.

For a correct and safe installation, it is crucial to select the proper ring type and size for the shaft or housing groove, and to use specific assembly tools.

To guarantee optimum performance, it is essential to select the appropriate spiral type, material, and number of turns suitable for the load and working environment. This allows us to adapt to the specific requirements of each client and sector. We have standard solutions in stock and also offer custom manufacturing, always ensuring the quality, traceability, and international compatibility that characterize all OSN products.
