3M 7010308273 Abrasive Belt 126x12 Inch Aluminum Oxide

Product Description

The 3M 7010308273 is a Trizact 253FA coated abrasive belt designed for flat finishing and centerless grinding applications. It uses microreplicated aluminum oxide mineral bonded with resin onto an XF-weight polyester cloth backing that is both waterproof and durable. The XF-weight backing provides the rigidity needed for high-contact grinding while retaining enough flexibility to conform to irregular profiles. This belt measures 126 inches in length and 12 inches in width. It is installed and used by metalworking fabricators, tool and die shops, and finishing technicians working on production or job-shop lines.

This belt is engineered for wet intermediate and fine finishing passes on a broad range of metals. Typical applications include surface finishing on stainless steel, carbon steel, aluminum, nickel alloys, cobalt steel, copper, and brass. It is well suited to centerless belt grinders and wide flat-platen finishing machines where consistent, repeatable scratch patterns are required across the full belt width.

Key Features

• Microreplicated aluminum oxide mineral construction reduces risk of uneven finishes and extends cut life
• XF-weight polyester cloth backing withstands wet and dry use while conforming to irregular workpiece profiles
• Waterproof backing supports wet intermediate and fine finishing operations
• Compatible with stainless steel, carbon steel, aluminum, nickel alloys, cobalt steel, copper, and brass
• Available in multiple splice styles to match machine and application requirements

Compatibility

Designed for use on flat-platen and centerless belt finishing machines that accept a 126-inch by 12-inch abrasive belt. Suitable for metalworking applications requiring intermediate to fine surface finishing on ferrous and non-ferrous metals.

Installation Notes

Installation is performed by machine operators or maintenance technicians following the equipment manufacturer's belt-change procedure. Power down and lock out the machine before removing the worn belt and seating the new one. Verify belt tracking and tension per the grinder manufacturer's specifications before resuming operation. When using in wet applications, confirm that the machine's coolant system is compatible with the belt backing before running.
