It uses 3M microreplication technology, where micron-graded aluminum oxide particles are formed into three-dimensional pyramids and bonded onto an X weight cloth backing. As the abrasive pyramids wear during use, fresh cutting mineral is continuously exposed. This self-renewing action delivers a consistent cut rate and a predictable, fine surface finish from start to finish. The belt measures 48 inches in length and 24 inches in width. It is suited for metalworking environments where controlled finishes are required before plating, buffing, or final surface treatment.\u003c\/p\u003e\u003cp\u003eThis belt is used in intermediate and fine finishing operations on metal workpieces, including pre-plate and pre-buff surface preparation. The flexible X weight cloth backing conforms to contours, making it appropriate for both flat stock and profiled parts. The three-dimensional abrasive structure is particularly well suited to robotic and automated grinding and finishing systems, where consistent finish throughout the full belt life is required. It is installed and operated by metal finishing technicians, fabricators, and production grinding specialists.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicroreplication technology forms aluminum oxide into self-sharpening pyramidal structures for consistent cut and finish\u003c\/li\u003e\n\u003cli\u003eSelf-sharpening design runs cooler than conventional abrasive belts, reducing heat-related workpiece distortion\u003c\/li\u003e\n\u003cli\u003eFlexible X weight cloth backing conforms to contoured surfaces for uniform finish\u003c\/li\u003e\n\u003cli\u003eThree-dimensional abrasive structure maintains consistent finishes throughout belt life in robotic applications\u003c\/li\u003e\n\u003cli\u003eProduces finer surface finishes than conventionally electrostatically coated abrasives\u003c\/li\u003e\n\u003cli\u003eSuited for intermediate finishing and fine polishing prior to plating or buffing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on belt grinders and finishing machines that accept 48-inch by 24-inch abrasive belts.

Power down and lock out the belt grinder or finishing machine before changing belts, following OSHA lockout\/tagout procedures. Confirm belt tracking direction arrows align with machine drive direction before starting. Inspect the contact wheel and platen for wear or damage prior to mounting a new belt.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Trizact Microreplication\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: X Weight Cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Length\u003c\/strong\u003e: 48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Width\u003c\/strong\u003e: 24 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.145 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: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000139280\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343328051506,"sku":"7000139280","price":832.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530221.jpg?v=1782020194","url":"https:\/\/voomisupply.com\/products\/3m-7000139280-trizact-237aa-abrasive-belt-48x24-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
