Self-locking and push-on retaining rings offer a compact, cost-effective solution for axial retention, without the need for a machined groove. Designed with specialized prongs, notches, or indentations on their inner or outer diameters, these rings grip securely to shafts or bores and resist displacement under vibration or dynamic loads. They install quickly without tools, making them ideal for high-volume production and assemblies with low thrust loads.
