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

15-7 PH Stainless Steel—Combine strength with corrosion resistance. While harder than most stainless steel rings, these will dent and scratch easier than carbon steel ones.

Beryllium Copper—Nonmagnetic rings that conduct electricity and have good corrosion and wear resistance. Do not use in direct contact with acetylene.

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

15-7 PH Stainless Steel—Combine strength with corrosion resistance. While harder than most stainless steel rings, these will dent and scratch easier than carbon steel ones.

Beryllium Copper—Nonmagnetic rings that conduct electricity and have good corrosion and wear resistance. Do not use in direct contact with acetylene.

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.

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

15-7 PH Stainless Steel—Combine strength with corrosion resistance. While harder than most stainless steel rings, these will dent and scratch easier than carbon steel ones.

Reinforced Side-Mount External Retaining Rings

These rings resist vibration, shock, and speed. Standard side-mount rings make their lowest points of contact at the shaft's centerline, while these rings establish contact below it. That difference results in 40% greater RPM limits or more to keep your ring from flying off the shaft. Push into the groove with a side-mount retaining ring tool.

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

15-7 PH Stainless Steel—Combine strength with corrosion resistance. While harder than most stainless steel rings, these will dent and scratch easier than carbon steel ones.

Beryllium Copper—Nonmagnetic rings that conduct electricity and have good corrosion and wear resistance. Do not use in direct contact with acetylene.

Tight-Clearance Side-Mount External Retaining Rings

Fit into tight spaces where other rings can’t. Also known as C-Style rings, these have a small shoulder to slide onto shafts in compact assemblies, such as instrument panels, actuator systems, and small robotic joints. Push into the groove with a side-mount retaining ring tool.

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

15-7 PH Stainless Steel—Combine strength with corrosion resistance. While harder than most stainless steel rings, these will dent and scratch easier than carbon steel ones.

Self-Locking External Retaining Rings

No groove needed. These rings are up to 50% thicker than standard rings to grip shafts on their own. They can't handle as much force as rings in grooves, however, so use them in applications with lighter loads. 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-Yellow-Chromate-Plated Carbon Steel—These rings are strong with good wear resistance. They provide some corrosion resistance, but not as much as stainless steel rings.

15-7 PH Stainless Steel—Combine strength with corrosion resistance. While harder than most stainless steel rings, these will dent and scratch easier than carbon steel ones.

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.

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.

Tight-Hold Bowed External Retaining Rings

If a groove is imperfect or wears over time, these bowed rings will outlast standard external rings. When flattened, they push back like a spring to maintain a secure and steady hold. Open with retaining ring pliers, pass them over the end of a shaft, and release to spring into a groove.

Ring ID is measured with the ring uninstalled.

Install from the side and these rings hold on tight for the long haul. If a groove is imperfect or wears over time, these bowed rings will outlast standard rings.
