Spiral Internal Retaining Rings
These coiled rings can be wound into place without tools. They make 360° contact with the bore so there is no gap. Ring OD is measured with the ring uninstalled.
1060-1090 spring steel rings are an economical choice with good strength.
18-8 stainless steel rings have good corrosion resistance.
Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.
