It runs a 50-grit aluminum oxide abrasive grain on a closed-coat layout, which keeps cutting edges dense across the full belt surface for consistent stock removal. The X-weight cloth backing resists tearing and flexing under load, making it well-suited for heavy grinding, weld blending, and rough shaping work on metal and wood. This belt is rated for dry use only. It measures 3 inches wide by 132 inches in overall length and is sold individually.\u003c\/p\u003e\u003cp\u003eThis belt is used in industrial and trade shop environments where high-material-removal abrasive work is performed. The 50-grit coarse grade makes it appropriate for initial surface preparation, deburring, weld seam blending, and shaping on ferrous and non-ferrous metals as well as hardwoods. It fits standard belt sander setups that accept a 3-inch by 132-inch belt. HVAC sheet metal fabricators, pipefitters, and general metalworking trades commonly use this grit range for prep work before moving to finer finishing stages.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e50-grit coarse aluminum oxide grain for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eClosed-coat construction delivers consistent cut across the full belt surface\u003c\/li\u003e\n\u003cli\u003eX-weight cloth backing provides high tensile strength and tear resistance under load\u003c\/li\u003e\n\u003cli\u003eDry-use rated — not compatible with wet or coolant-assisted grinding applications\u003c\/li\u003e\n\u003cli\u003eSeries R228 construction for uniform grain adhesion and long belt life\u003c\/li\u003e\n\u003cli\u003e3 inches wide by 132 inches OAL to fit standard belt sander configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for belt sanders accepting a 3-inch by 132-inch abrasive belt.

Verify belt tracking direction — most coated abrasive belts have a recommended run direction marked by an arrow on the inner face. Inspect the contact wheel, platen, and idler for wear before mounting a new belt. Do not exceed the rated RPM of the machine when selecting replacement belts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Width\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Length (OAL)\u003c\/strong\u003e: 132 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\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoat Density\u003c\/strong\u003e: Closed\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\u003eWet\/Dry Operation\u003c\/strong\u003e: Dry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R228\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191507\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: 78072721890\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540666024242,"sku":"78072721890","price":35.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3516bf6b9c436b7d4c11c7e3209e2aae.jpg?v=1785861317","url":"https:\/\/voomisupply.com\/products\/norton-78072721890-abrasive-belt-50-grit-3x132-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
