Measuring 15\/16 inches in diameter, this ball holds a diameter deviation of no more than 0.00005 inches and a sphericity tolerance of 0.000025 inches. Hardness runs 62 to 66 HRC, making it suitable for load-bearing and wear-resistant environments. Machinists, maintenance technicians, and industrial assembly professionals use Grade 25 balls in bearings, valves, gauges, and precision mechanical assemblies where dimensional accuracy is critical.\u003c\/p\u003e\n\u003cp\u003eGrade 25 chrome steel balls are commonly specified in anti-friction bearing assemblies, ball screws, check valves, and precision measurement fixtures across both light industrial and heavy manufacturing settings. The 15\/16-inch diameter fits standard bearing races and valve seats designed around this nominal size. This package contains 15 balls per unit, supplied as a quantity lot suitable for service replacement, production assembly, or maintenance stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 25 precision grade with 0.00005-inch diameter deviation tolerance\u003c\/li\u003e\n  \u003cli\u003eSphericity tolerance of 0.000025 inches for consistent contact geometry\u003c\/li\u003e\n  \u003cli\u003e62 to 66 HRC surface hardness for wear and load resistance\u003c\/li\u003e\n  \u003cli\u003eChrome steel construction for corrosion resistance in typical industrial environments\u003c\/li\u003e\n  \u003cli\u003e15\/16-inch diameter compatible with standard bearing and valve seat dimensions\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 15 balls per lot\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or production-use Grade 25 chrome steel ball for bearing assemblies, check valves, ball screws, and precision mechanical components requiring a 15\/16-inch nominal ball diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of precision balls into bearing races or valve seats should be performed by qualified mechanical technicians using clean, lint-free handling procedures to avoid contaminating the ball surface or seating area. De-energize and de-pressurize any system before removing or replacing balls in live assemblies. Avoid impact installation methods that could alter sphericity or surface finish. Follow equipment manufacturer specifications for lubrication and preload when reseating into bearing assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Chrome Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Deviation\u003c\/strong\u003e: 0.00005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSphericity\u003c\/strong\u003e: 0.000025 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 62-66 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 15 balls\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 30102304\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20127\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694220050738,"sku":"20127","price":58.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fb8c25de1b533082e7e1ab9ced93333d.jpg?v=1788321798","url":"https:\/\/voomisupply.com\/products\/value-collection-20127-chrome-steel-ball-grade-25-15-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
