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.
