    Tight-Hold Bowed External Retaining Rings

    Image of Product. Front orientation. Retaining Rings. 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.
    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.
