Made from spring steel with a zinc finish, it seats in a machined groove to axially retain shafts, bearings, or other components inside a housing bore. Ring thickness is 0.042 inches, groove width is 0.046 inches, and free outside diameter is 0.971 inches. The zinc finish provides basic corrosion resistance in typical indoor mechanical environments. This ring is installed by machinists, maintenance technicians, and assembly professionals working on rotating or linear motion assemblies where a secure internal retainer is required.\u003c\/p\u003e\u003cp\u003eThis ring fits applications where an internal groove is cut into a bore to retain a component without the use of threaded fasteners or adhesives. Common use cases include gearboxes, pump housings, electric motor end bells, hydraulic cylinders, and general industrial assemblies. The groove depth of 0.028 inches and groove width of 0.046 inches must be machined to specification for proper seating and rated load capacity. Suitable for both OEM production assembly and MRO replacement service.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInternal snap ring design seats in bore groove to retain components axially\u003c\/li\u003e\n\u003cli\u003eSpring steel construction with material grade 1060\/1090 for consistent snap force and durability\u003c\/li\u003e\n\u003cli\u003eZinc finish for basic corrosion protection in standard indoor mechanical environments\u003c\/li\u003e\n\u003cli\u003eThrust load capacity rated at 2080 pounds at groove safety factor and 5227 pounds at ring safety factor\u003c\/li\u003e\n\u003cli\u003eHardness rated Rockwell 30N 66-71 for reliable spring-back performance\u003c\/li\u003e\n\u003cli\u003eConforms to SAE 1060-1090 and ISO 13485:2016 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style internal snap retaining ring for 7\/8-inch bore applications where groove dimensions of 0.046-inch width and 0.028-inch depth are machined to specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires snap ring pliers sized for internal rings.
