External retaining ring for axial assembly into machined grooves on shafts. The tapered section design provides uniform circular deformation, enabling complete contact and a tight fit in the groove. Materials and temperature ranges - Steel: Carbon spring steel SAE 1060-1090; -100°F to 500°F - Stainless steel: corrosion resistant; -100°F to 900°F; suitable for higher heat applications Material specification - Steel option: Carbon spring steel SAE 1060-1090 Key benefits - Reliable axial retention on shafts with secure groove engagement - Tapered section design delivers uniform deformation for consistent contact and tightness - Choice of materials to match environment: standard steel for general use; stainless steel for corrosion resistance and higher heat Size and compatibility - Available in multiple sizes to fit corresponding shaft groove dimensions - Designed for use with machined grooves on shafts Practical applications - Securing a pulley or gear on a driveshaft in industrial machinery where moderate heat and vibration are present - Retaining a sprocket or hub on a shaft in conveyor or equipment with exposure to moisture or chemicals - High temperature or corrosive environments where stainless steel offers enhanced durability, such as near furnaces, exhaust systems, or chemical processing areas
