3M 7000118655 Trizact 237AA Abrasive Belt 48x2 Inch Ao

Product Description

The 3M 7000118655 is a Trizact 237AA abrasive belt designed for intermediate finishing and fine polishing applications across metal fabrication and surface preparation workflows. It uses 3M microreplication technology, where micron-graded aluminum oxide mineral is formed into three-dimensional pyramids and bonded to an X-weight cloth backing. As the pyramids wear during use, fresh, sharp abrasive is continuously exposed, delivering a consistent cut rate and predictable surface finish throughout the life of the belt. The belt measures 48 inches in length and 2 inches in width and is gray in color. Fabricators, toolmakers, and finishing technicians work with this product in both manual and automated setups.

This belt is used in intermediate finishing and fine polishing operations prior to plating or buffing on metal components. The flexible cloth backing conforms to contoured workpiece geometry, making it suitable for parts with complex profiles. Its three-dimensional abrasive structure produces finer finishes than conventional electrostatically coated abrasives and maintains consistent results in robotic and automated finishing systems where repeatability is critical.

Key Features

• Microreplication technology forms aluminum oxide mineral into self-sharpening abrasive pyramids
• Continuously exposes fresh mineral as pyramids wear, maintaining consistent cut and finish
• Runs cooler than conventional abrasives, reducing heat buildup on workpieces
• Flexible X-weight cloth backing conforms to contoured and complex part surfaces
• Produces finer finishes than conventional electrostatically coated abrasive belts
• Consistent three-dimensional structure supports repeatable results in robotic finishing applications

Compatibility

Designed for use on belt finishing machines that accept a 48-inch by 2-inch abrasive belt. Suited for intermediate finishing and fine polishing of metal components prior to plating or buffing operations.

Installation Notes

Installation is performed by metalworking or finishing technicians familiar with belt-driven abrasive equipment. Power down and de-energize the finishing machine completely before changing belts. Verify belt tracking alignment after installation and before resuming operation. Follow the equipment manufacturer's guidelines for belt tension and guard placement.
