Internal Retaining Rings

Secure components inside a housing or bore with our go-to internal 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. Squeeze with retaining ring pliers and release into a groove.

Ring OD 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.

Spiral Internal 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 OD 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.

High-Load Internal Retaining Rings

Thick rings manufactured for high-load applications, from power-generation systems to earth movers. Compared to the standard internal retaining rings, these have up to twice the thrust load capacity. Squeeze with retaining ring pliers and release into a groove inside a bore or housing.

Ring OD 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.

Tight-Clearance Inverted Internal Retaining Rings

The lugs on these rings point outward, so they won't snag on other parts and have better clearance than standard internal rings. Shaped in the most common style, they are tapered so the thickest section is opposite their opening for a secure 360-degree hold. Squeeze with retaining ring pliers and release into a groove inside a bore or housing.

Ring OD 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 Internal Retaining Rings

Stand up to stronger forces with more layers than the standard internal spiral option. These rings usually have 20% more thrust load capacity than the standard. No tools needed for installation. Spread apart, insert one end into the groove, then collapse the rest of it into place.

Ring OD 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.
