It measures 11\/16 inches in diameter and is produced to tight dimensional tolerances, making it suitable for applications where surface finish, sphericity, and size consistency are critical. The ball carries a hardness rating of 57 to 61 HRC and holds a sphericity tolerance and diameter deviation of 0.0005 inches. These characteristics make it appropriate for use in bearings, valves, check assemblies, and precision mechanical components across industrial and mechanical trade applications.\u003c\/p\u003e\n\u003cp\u003eThis precision ball is used in residential and commercial mechanical systems wherever a hardened, corrosion-resistant spherical element is required. Typical applications include ball valve assemblies, bearing races, check valves, and flow-control components. The 440-C stainless steel alloy provides good corrosion resistance alongside high hardness, making it well suited to environments with exposure to moisture or mild chemicals. Sold in packages of 10 units, this part is appropriate for maintenance shops, mechanical contractors, and OEM assembly operations requiring consistent lot quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e440-C stainless steel construction provides high hardness and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eGrade 100 precision rating ensures consistent dimensional quality across the lot\u003c\/li\u003e\n  \u003cli\u003e57 to 61 HRC hardness range suitable for load-bearing and wear-resistance applications\u003c\/li\u003e\n  \u003cli\u003e0.0005 inch sphericity tolerance for tight-tolerance bearing and valve fitment\u003c\/li\u003e\n  \u003cli\u003e0.0005 inch diameter deviation for reliable dimensional consistency\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 10 for efficient stocking and assembly use\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 ball valve assemblies, bearing races, and check valve mechanisms requiring a Grade 100, 440-C stainless steel ball with an 11\/16 inch diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by mechanical technicians or machinists working on valve, bearing, or fluid-control assemblies. Depressurize and isolate any fluid or pneumatic system completely before replacing internal ball components. Handle precision balls with clean, dry gloves or tools to avoid surface contamination that could affect seating or bearing performance. Follow applicable ASME or OEM assembly specifications for seating torque and housing tolerances.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 440-C Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Deviation\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSphericity\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 57 to 61 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 100\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: 30102305\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: 20187\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690377543986,"sku":"20187","price":31.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/41516da48a6fe33d81f62d7ce4e606e0.jpg?v=1788269593","url":"https:\/\/voomisupply.com\/products\/value-collection-20187-440-c-steel-precision-ball-11-16-in-grade-100","provider":"Voomi Supply","version":"1.0","type":"link"}
