The Rotor Clip E-25ST ZD is a radially assembled, external E-style retaining ring designed for 0.25" shaft diameters. Manufactured from high-strength carbon steel (SAE 1060-1090), it features a zinc dichromate finish that offers enhanced corrosion resistance, making it suitable for applications exposed to moisture or corrosive environments. The ring's 0.025" thickness and 0.21" groove diameter ensure a secure fit, accommodating lower thrust loadings effectively. Its three-prong design provides a shoulder for effective retention of assemblies, and the absence of lug holes allows for easy installation using retaining ring applicators. This design also enables installation without turning the tool, as the ring "snaps" when properly seated in the groove. The E-25ST ZD is an economical alternative to axially assembled external tapered section rings, offering a reliable solution for retaining components in various industrial applications.
