It fits a 2.5-inch shaft diameter and seats into a groove that measures 2.36 inches in diameter and 0.086 inches wide. The ring is manufactured from SAE 1060-1090 carbon steel and finished with a yellow zinc dichromate coating for corrosion resistance. With a hardness rating of 47-52 HRC, this ring provides reliable axial retention under load. Mechanical assemblers, maintenance technicians, and industrial tradespeople install this ring wherever shaft-mounted components require a positive stop or retention point.\u003c\/p\u003e\n\u003cp\u003eThis external retaining ring is suited for use on 2.5-inch shafts in industrial and mechanical equipment, including pump assemblies, gearboxes, motors, and drive components. It is installed into a precision-machined external groove on the shaft. The ring conforms to SAE 1060-1090 and UNS G10600-G10900 standards and is produced to ISO 13485:2015 quality management requirements, making it appropriate for demanding mechanical and instrumentation applications. It is sold in a minimum order quantity of 5 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 2.5-inch shaft diameter with a 2.36-inch groove diameter\u003c\/li\u003e\n  \u003cli\u003eSAE 1060-1090 carbon steel construction with 47-52 HRC hardness\u003c\/li\u003e\n  \u003cli\u003eYellow zinc dichromate finish provides corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eRing thickness of 0.078 inches with a tight tolerance of plus or minus 0.003 inches\u003c\/li\u003e\n  \u003cli\u003eGroove width of 0.086 inches with a tolerance of 0.000 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eManufactured to ISO 13485:2015 quality management standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style external retaining ring for 2.5-inch shafts requiring a groove diameter of 2.36 inches.
