Measuring 12 mm in overall diameter, this ball meets tight dimensional tolerances with a diameter deviation of 0.00005 inches and a sphericity of 0.000025 inches. Hardness is rated at 62 to 66 HRC, making it well-suited for high-load and high-wear environments. Licensed technicians, machinists, and maintenance professionals working with precision assemblies rely on components at this tolerance class to maintain system integrity and minimize wear-related failures.\u003c\/p\u003e\u003cp\u003eGrade 25 chrome steel balls are used in ball bearings, linear motion systems, check valves, pumps, and general industrial assemblies where close dimensional accuracy is required. The metric 12 mm diameter fits standard metric bearing races and housings common in commercial and industrial equipment. This part is sold in packages of 10, making it practical for both single-unit repairs and small-batch replacements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 25 precision classification with 0.00005-inch diameter deviation\u003c\/li\u003e\n\u003cli\u003eSphericity of 0.000025 inches for consistent rolling accuracy\u003c\/li\u003e\n\u003cli\u003eHardness rated 62 to 66 HRC for high-load and wear-resistant applications\u003c\/li\u003e\n\u003cli\u003eChrome steel construction provides corrosion resistance and surface durability\u003c\/li\u003e\n\u003cli\u003eMetric 12 mm diameter fits standard metric bearing and valve assemblies\u003c\/li\u003e\n\u003cli\u003eSold in a package of 10 units\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for metric precision bearing assemblies and industrial components requiring a Grade 25, 12 mm chrome steel ball.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by machinists, bearing technicians, or qualified maintenance personnel. Ensure the mating bearing race, housing, or seat is clean and free of debris before seating the ball. Do not force the ball into an undersized bore, as this can damage the seating surface and compromise dimensional accuracy. Handle precision-grade balls with clean tools or gloves to avoid surface contamination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 12 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: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 30102304\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 20154\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690560061746,"sku":"20154","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf68e5501ee3e06abf356cda80565c1e.jpg?v=1788271701","url":"https:\/\/voomisupply.com\/products\/value-collection-20154-chrome-steel-ball-grade-25-12mm","provider":"Voomi Supply","version":"1.0","type":"link"}
