Tight-Hold Bowed Internal Retaining Rings
 |
If a groove is imperfect or wears over time, these bowed rings will outlast standard internal rings. When flattened, they push back like a spring to maintain a secure and steady 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.

Tight-Hold Bowed Side-Mount External Retaining Rings
 |
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. When flattened, they push back like a spring to maintain a secure and steady hold. 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.
