3M 7010364998 Trizact 217EA Abrasive Belt 118x3 Inch Ao

Product Description

The 3M 7010364998 is a Trizact 217EA coated abrasive belt designed for intermediate finishing and fine polishing operations on metal and contoured surfaces. It uses 3M microreplicated technology, in which micron-graded aluminum oxide particles are formed into precise pyramidal structures on a JE-weight rayon cloth backing. As the pyramids wear during use, fresh, sharp mineral is continuously exposed, delivering a consistent cut rate and a predictable fine finish across the full life of the belt. At 118 inches long and 3 inches wide, it fits wide belt and robotic grinding setups where repeatable results are critical.

This belt is suited for metalworking applications requiring controlled surface finishing before plating, buffing, or polishing. Its flexible JE-weight rayon backing conforms to contoured and complex geometries, making it a common choice for finishing stainless steel, aluminum, and other metals in both manual and automated robotic lines. It performs best under light pressure, where the abrasive structure can self-dress and maintain a consistent surface finish throughout the belt life. A built-in grinding aid helps reduce heat buildup to minimize warping and discoloration on heat-sensitive workpieces.

Key Features

• Microreplicated aluminum oxide pyramids continuously expose fresh mineral for consistent cut throughout belt life
• JE-weight rayon cloth backing flexes over contoured surfaces for uniform contact and finish
• Grinding aid reduces heat buildup, helping prevent warping and discoloration on metal workpieces
• Engineered for light-pressure applications where abrasive self-dressing maintains cut rate
• Produces finer finishes than conventional coated abrasive belts
• Consistent performance makes this belt well-suited for robotic and automated finishing systems

Compatibility

Designed for use on wide belt sanders and robotic finishing equipment that accept 118 inch by 3 inch abrasive belts; appropriate for intermediate finishing and pre-plate or pre-buff polishing of metal workpieces.

Installation Notes

Installation should be performed by qualified equipment operators following the belt sander manufacturer guidelines for belt tracking and tensioning. Power down and lockout the machine before mounting or removing the belt. Inspect the belt for tears or edge damage before use. Always run the belt in the direction of the arrow marked on the backing if one is present.
