Manufactured from SAE 1060-1090 carbon steel and finished with a yellow zinc dichromate coating for corrosion resistance, this ring delivers a hardness rating of 47-52 HRC for dependable retention under load. With a groove diameter of 2.12 inches and a ring thickness of 0.078 inches, it is engineered to tight dimensional tolerances. Machinists, maintenance technicians, and mechanical assembly professionals install this type of ring in rotating shaft assemblies, drive trains, and power transmission components.\u003c\/p\u003e\n\u003cp\u003eThis external retaining ring is suited for industrial and mechanical applications where a positive, reusable shaft stop is required. Typical installations include pump shafts, gearbox assemblies, motor shafts, and conveyor drive components. The zinc dichromate finish provides a baseline level of environmental protection in moderate-exposure environments. The ring conforms to SAE 1060-1090 and UNS G10600-G10900 fastener standards, and the manufacturing process is aligned with ISO 13485:2015 quality management requirements, making it appropriate for precision-critical assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 2-1\/4 inch (2.2500 inch decimal) shaft diameter with a 2.12 inch groove diameter\u003c\/li\u003e\n  \u003cli\u003eSAE 1060-1090 carbon steel construction rated at 47-52 HRC hardness\u003c\/li\u003e\n  \u003cli\u003eYellow zinc dichromate finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eRing thickness of 0.078 inches with a tolerance of plus or minus 0.003 inches for consistent groove fit\u003c\/li\u003e\n  \u003cli\u003eGroove width of 0.086 inches and groove depth of 0.065 inches for precise seating\u003c\/li\u003e\n  \u003cli\u003eMeets SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2015 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 shafts with a 2-1\/4 inch nominal diameter and a groove diameter of 2.12 inches machined to SAE standard tolerances.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExternal retaining rings of this type are installed and removed using snap ring pliers sized for external rings. Disengage all power and relieve any load on the shaft assembly before servicing. Inspect the shaft groove for burrs or damage before installation, as groove defects can compromise ring retention.
