Built on an X-weight cloth backing, it delivers the rigidity and durability needed for demanding grinding and sanding applications. The disc uses aluminum oxide abrasive grain at a coarse 50 grit, making it well suited for stock removal, weld blending, and surface preparation on metal, wood, and composite materials. At 20 inches in diameter, it is sized for large stationary disc sanders and floor equipment. Licensed trades and industrial finishing technicians are the primary installers and users of this product.\u003c\/p\u003e\u003cp\u003eThis PSA disc is intended for use on large-format stationary disc sanders, floor sanders, and industrial sanding machines that accept 20-inch PSA-mount abrasives. The coarse 50-grit cut rate makes it appropriate for initial material removal passes, leveling uneven surfaces, or preparing substrates before finishing with finer grits. It is commonly used in woodworking shops, metal fabrication facilities, flooring operations, and industrial production environments. The flexible cloth backing conforms moderately to the work surface, helping maintain consistent abrasive contact across the full disc face.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e20-inch diameter fits large stationary and floor-mount PSA disc sanders\u003c\/li\u003e\n\u003cli\u003e50-grit aluminum oxide grain provides aggressive coarse-grade stock removal\u003c\/li\u003e\n\u003cli\u003eX-weight cloth backing offers high tensile strength and flexibility under load\u003c\/li\u003e\n\u003cli\u003ePressure-sensitive adhesive mount for secure attachment without mechanical fasteners\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — suited for solid-platen machines without dust extraction ports\u003c\/li\u003e\n\u003cli\u003eBrown disc color; part of the NORTON R228 series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard consumable for large-format stationary disc sanders and industrial sanding equipment that accept 20-inch PSA abrasive discs with solid platens.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machine operators or maintenance technicians. Power down and lock out the sanding machine before removing the spent disc or installing a new one. Peel the release liner from the PSA backing and apply the disc to a clean, dry platen, pressing firmly from the center outward to eliminate air pockets. Verify the disc is fully seated before resuming operation, and inspect the adhesive bond periodically during heavy use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Pressure-Sensitive Adhesive (PSA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum Holes\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R228\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.78 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: NORTON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66261136711\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543035380018,"sku":"66261136711","price":40.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b144e259ebed0b21ab65756c41b2c56.jpg?v=1785914209","url":"https:\/\/voomisupply.com\/products\/norton-66261136711-psa-disc-20-in-50-grit-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
