With an overall diameter of 13.0 mm, a diameter deviation of 0.00005 inches, and a sphericity of 0.000025 inches, this ball meets the exacting standards used in precision bearing assemblies, gauging equipment, and industrial motion components. Hardness ranges from 62 to 66 HRC, indicating a fully hardened chrome steel construction suited for load-bearing and wear-resistant service. Sold in a package quantity of 5.\u003c\/p\u003e\n\u003cp\u003eGrade 25 chrome steel balls are commonly used in precision ball bearings, check valves, linear motion systems, and instrumentation assemblies across industrial, hydraulic, and mechanical applications. The metric 13.0 mm diameter fits a range of standard metric bearing housings and valve seats. These balls are appropriate for use by maintenance technicians, machine builders, bearing specialists, and precision equipment service professionals working in manufacturing, hydraulics, and industrial automation environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 25 precision rating with 0.00005 inch diameter deviation\u003c\/li\u003e\n  \u003cli\u003eSphericity tolerance of 0.000025 inches for consistent roundness\u003c\/li\u003e\n  \u003cli\u003e62 to 66 HRC hardness for high wear resistance and load capacity\u003c\/li\u003e\n  \u003cli\u003eChrome steel construction suitable for standard bearing and valve applications\u003c\/li\u003e\n  \u003cli\u003eMetric sizing at 13.0 mm overall diameter\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 5 to support small-quantity service and replacement needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service component for precision bearing assemblies, check valves, and industrial machinery requiring Grade 25 chrome steel balls with a 13.0 mm metric diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by bearing technicians or mechanical assemblers familiar with precision component handling. Clean mating surfaces and housings before installation to prevent contamination that could affect tolerance fit or surface finish. Avoid impact installation methods that could alter sphericity or damage the hardened surface. Consult equipment manufacturer specifications to confirm dimensional and grade requirements before replacing existing balls.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 13.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Chrome Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 62 to 66 HRC\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\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\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: 20155\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697638572338,"sku":"20155","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/661bc9e99a679716078a42add04360db.jpg?v=1788353689","url":"https:\/\/voomisupply.com\/products\/value-collection-20155-chrome-steel-ball-grade-25-13mm","provider":"Voomi Supply","version":"1.0","type":"link"}
