Single-Turn Spiral External Retaining Rings
Slide these rings into place with one twist—no tools required—for applications with high thrust loads. Ring ID 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 471 rings meet international standards for groove specifications in retaining rings.
Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.
