As the outer layer of each pyramid wears away, fresh, sharp abrasive mineral is continuously exposed. The result is a consistent cut rate and a predictable fine finish from the first pass to the last. The belt measures 15.5 inches in length and 3.5 inches in width. Flexible cloth construction allows the belt to conform to contoured workpiece geometry without losing uniformity of finish.\u003c\/p\u003e\u003cp\u003eThis belt is suited to intermediate finishing and fine polishing operations that precede plating, buffing, or similar surface-preparation steps. The three-dimensional abrasive structure makes it a reliable choice in robotic and automated belt-sanding systems where consistent, repeatable surface finish is critical across high production volumes. Manual applications in metal fabrication and finishing shops also benefit from the cooler-running pyramid design, which reduces heat buildup at the workpiece surface. Licensed trade professionals and industrial finishing technicians are the primary installers and operators.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicroreplication technology forms aluminum oxide into self-sharpening pyramidal abrasive structures\u003c\/li\u003e\n\u003cli\u003eContinuously exposes fresh mineral as pyramids wear, maintaining consistent cut throughout belt life\u003c\/li\u003e\n\u003cli\u003eRuns cooler than conventional coated abrasives, reducing heat buildup on the workpiece\u003c\/li\u003e\n\u003cli\u003eFlexible X-weight cloth backing conforms to contoured surfaces for uniform finish\u003c\/li\u003e\n\u003cli\u003eThree-dimensional design delivers repeatable finishes in robotic and automated applications\u003c\/li\u003e\n\u003cli\u003eProduces finer surface finishes than conventionally electrostatically coated abrasive belts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use abrasive belt for belt sanders and finishing machines that accept a 15.5-inch by 3.5-inch belt in intermediate finishing and fine polishing applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tensioning of abrasive belts should be performed by qualified finishing equipment operators following the machine manufacturer's guidelines. Power down and lock out the sanding or grinding unit before mounting or removing the belt. Verify that belt travel direction matches the arrow marked on the backing, if present, to ensure proper grain orientation. Wear appropriate PPE including eye protection and dust respiratory equipment during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Length\u003c\/strong\u003e: 15.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Width\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: X-Weight Cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Technology\u003c\/strong\u003e: Microreplication (Trizact)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000028338\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346892652850,"sku":"7000028338","price":751.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524911.jpg?v=1782093803","url":"https:\/\/voomisupply.com\/products\/3m-7000028338-abrasive-belt-15-5-in-x-3-5-in-ao-cloth","provider":"Voomi Supply","version":"1.0","type":"link"}
