3M 7000118684 Abrasive Belt 132x3 Inch Ao Cloth Gray

Product Description

The 3M 7000118684 is a Trizact 237AA abrasive belt engineered for intermediate finishing and fine polishing applications in metalworking and fabrication environments. It uses 3M microreplication technology, where micron-graded aluminum oxide particles are formed into precise three-dimensional pyramids and bonded to an X-weight cloth backing. As the pyramids wear during use, fresh sharp mineral is continuously exposed, delivering a consistent cut rate and predictable finish quality throughout the belt's service life. At 132 inches long and 3 inches wide, this belt is sized for wide belt sanders and automated finishing equipment.

This belt is suited for metal finishing operations including intermediate stock removal and fine polishing prior to plating or buffing. The flexible X-weight cloth backing conforms to contoured surfaces, making it effective for both flat and profiled workpieces. It is widely used in robotic and automated belt finishing systems where consistent, repeatable surface finish is critical across long production runs. Fabricators, tool and die shops, and finishing operations handling ferrous and non-ferrous metals are the primary users.

Key Features

• Microreplication technology forms aluminum oxide into self-sharpening abrasive pyramids for consistent cut throughout belt life
• Three-dimensional pyramid structure runs cooler than conventional coated abrasives, reducing heat buildup at the workpiece
• Flexible X-weight cloth backing conforms to contoured and profiled surfaces
• Produces finer surface finishes than conventional electrostatically coated abrasive belts
• Consistent finish output makes it well suited for robotic and automated finishing applications
• Designed for intermediate finishing and fine polishing prior to plating or buffing operations

Compatibility

Designed for use on wide belt sanders and automated finishing machines accepting 132-inch by 3-inch abrasive belts in metalworking and fabrication applications.

Installation Notes

Belt installation and tensioning should be performed by qualified personnel following the equipment manufacturer's guidelines for belt sanders and finishing machines. Power down and lock out the machine before changing belts. Inspect the belt for tears, edge damage, or splice separation before mounting. Ensure belt tracking is adjusted properly before returning the machine to service.
