Measuring 0.25 inches in diameter, this ball meets tight dimensional tolerances with a diameter deviation of 0.00005 inches and a sphericity of 0.000025 inches. Hardness runs from 62 to 66 C on the Rockwell scale, making it suitable for high-load and high-wear environments. Chrome steel construction provides strong resistance to surface fatigue and deformation under repeated contact stress. Sold in a package quantity of 100 balls per order.\u003c\/p\u003e\u003cp\u003eGrade 25 chrome steel balls are widely used in ball bearings, check valves, pumps, flow controls, and industrial machinery. The tight sphericity and hardness range make them appropriate for applications where dimensional consistency directly affects performance, such as precision bearing assemblies and fluid metering components. These balls are used across HVAC, plumbing, fluid power, and general industrial equipment by mechanics, machinists, and assembly technicians.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 25 precision rating with 0.00005 inch diameter deviation\u003c\/li\u003e\n\u003cli\u003eSphericity of 0.000025 inches for consistent rolling and seating performance\u003c\/li\u003e\n\u003cli\u003eRockwell hardness of 62 to 66 C for high-load and wear-resistant applications\u003c\/li\u003e\n\u003cli\u003eChrome steel construction resists surface fatigue and corrosion under mechanical stress\u003c\/li\u003e\n\u003cli\u003e0.25 inch diameter in a convenient 100-piece package quantity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Grade 25 chrome steel ball for use in precision bearing assemblies, check valves, pumps, and mechanical components requiring a 0.25 inch diameter ball to ABMA Grade 25 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by machinists, bearing technicians, or mechanical assembly professionals. Before servicing any assembly containing these balls, depressurize and de-energize the system as required by applicable safety procedures. Handle precision balls with clean, dry tools to avoid surface contamination that could affect dimensional performance. Consult the OEM assembly specifications for seat dimensions and preload requirements before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Chrome Steel\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 to 66 C (Rockwell)\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: 100 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\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: 20107\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721013723442,"sku":"20107","price":15.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74cfdfc0fbf763c6af32d958d2d4081f.jpg?v=1788572275","url":"https:\/\/voomisupply.com\/products\/value-collection-20107-chrome-steel-ball-grade-25-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
