Heavy Duty Spiral Internal Retaining Rings
Thicker than standard spiral rings, these rings withstand greater forces. Wind them into place with two turns and they make 360° contact with the bore, so they’re best for high thrust loads. No tools required. 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.
DIN 472 rings meet an international standard for retaining ring groove specifications.
Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.
