The Rotor Clip SE-31ST PA is a radially assembled, external 'E' style retaining ring designed for 0.312" shaft diameters. Manufactured from carbon steel with a phosphate finish, this ring offers robust performance in various industrial applications. Its three-prong design ensures effective retention by making contact with the bottom of the groove, providing a shoulder for assemblies. The SE-31ST PA is ideal for applications requiring a secure and reliable method to retain components on shafts, especially where axial space is limited. Its design allows for easy installation using standard retaining ring applicators, eliminating the need for lug holes. This feature simplifies the assembly process and reduces potential points of failure. The phosphate coating enhances the ring's resistance to corrosion, extending its service life in demanding environments. With a maximum load capacity of 325 lbs and a limiting speed of 22,000 rpm, the SE-31ST PA is suitable for a wide range of applications, including automotive, machinery, and equipment manufacturing. By choosing the Rotor Clip SE-31ST PA, businesses can ensure secure component retention, reduce maintenance costs, and enhance the overall reliability of their products.
