Push-On External Retaining Rings
A
B
C
D
No groove required—press these rings onto the end of a shaft. Use them on unhardened shafts that are softer than the push ring. The ring bites into the metal to form an interference grip. Styles A, B, and C have teeth that dig into the shaft material, so expect minor scratching. Use a push nut installation tool (sold separately) to install rings, or install them manually.
1050 spring steel and 1060-1090 spring steel rings are an economical choice with good strength. A black finish is the result of a heat treatment to darken them—making them ideal for blending into dark backgrounds. However, these rings will rust if exposed to moisture. Black-phosphate finish is mildly corrosion resistant in dry environments. In wet environments, a zinc yellow-chromate plated finish has some corrosion resistance, and a zinc chromate plated finish has good corrosion resistance.
18-8 stainless steel rings have good corrosion resistance. A passivated finish adds protection against corrosion.
15-7 PH stainless steel rings have high strength with good corrosion resistance. Rings are passivated for added protection against corrosion.
