External Retaining Rings

Secure components on a shaft with our go-to external retaining rings. Shaped in the most common style, these are tapered so the thickest section is opposite their opening for a secure 360-degree hold. Open with retaining ring pliers, pass over the end of a shaft, then release them to spring into a groove.

Ring ID is measured with the ring uninstalled.

Phosphate-Coated Carbon Steel—The most popular choice, these are strong and wear resistant. Their finish adds some corrosion resistance, but only to minimal dampness.

Zinc-Plated Carbon Steel—These rings are strong with good wear resistance. They provide some corrosion resistance, but not as much as stainless steel rings.

1.4122 Stainless Steel—Corrosion and wear resistant rings that won't break down from rubbing against other metal.

High-Load External Retaining Rings

Thick rings manufactured for high-load applications, from power-generation systems to earth movers. Compared to standard external retaining rings, these usually have double the thrust load capacity. Open with retaining ring pliers, pass over the end of a shaft, then release them to spring into a groove.

Ring ID is measured with the ring uninstalled.

Phosphate-Coated Carbon Steel—The most popular choice, these are strong and wear resistant. Their finish adds some corrosion resistance, but only to minimal dampness.

Spiral External Retaining Rings

1 Turn

Coiled so you can install by hand without any tools. The coiling also keeps these rings from flying away during installation. Just insert one end into the groove, then wind the rest of the ring into place.

Ring ID is measured with the ring uninstalled.

Carbon Steel—The go-to choice. These rings have high strength and wear resistance, but they don't resist rust.

18-8 Stainless Steel—The choice for wet and outdoor environments. These rings resist rust, but they aren't as strong as carbon steel.

1 Turn—Slide into place with one twist. These rings are useful in areas where there's limited space for installation.

Tight-Clearance Inverted External Retaining Rings

The lugs on these rings point inward, so they won't snag on other parts and have better clearance than standard external rings. Shaped in the most common style, they are tapered so the thickest section is opposite their opening for a secure 360-degree hold. Open with retaining ring pliers, pass over the end of a shaft, then release them to spring into a groove.

Ring ID is measured with the ring uninstalled.

Phosphate-Coated Carbon Steel—The most popular choice, these are strong and wear resistant. Their finish adds some corrosion resistance, but only to minimal dampness.

High-Load Spiral External Retaining Rings

Thicker than standard external spiral rings, these have at least 20% more thrust load capacity. No tools needed for installation. Spread apart, insert one end into the groove, then collapse the rest of it into place.

Ring ID is measured with the ring uninstalled.

Carbon Steel—The go-to choice. These rings have high strength and wear resistance, but they don't resist rust.

18-8 Stainless Steel—The choice for wet and outdoor environments. These rings resist rust, but they aren't as strong as carbon steel.

External Retaining Rings Assortment

Stock up on our go-to external retaining rings in a range of sizes. Open with retaining ring pliers, pass over the end of a shaft, and release to spring the ring into the groove.

Phosphate-Coated Carbon Steel—The most popular choice, these are strong and wear resistant. Their finish adds some corrosion resistance, but only to minimal dampness.

Zinc-Plated Carbon Steel—These rings are strong with good wear resistance. They provide some corrosion resistance, but not as much as stainless steel rings.

1.4122 Stainless Steel—Corrosion and wear resistant rings that won't break down from rubbing against other metal.
