3M 7100026386 Trizact 217EA Abrasive Belt 132x3 Inch Ao

Product Description

The 3M 7100026386 is a Trizact 217EA coated abrasive belt designed for intermediate finishing and fine polishing applications. It uses microreplication technology in which micron-graded aluminum oxide particles are formed into precise pyramidal structures bonded to a JE-weight rayon cloth backing. As the pyramids wear during use, fresh abrasive mineral is continuously exposed, maintaining a consistent cut rate and producing repeatable, fine surface finishes throughout the life of the belt. At 132 inches long and 3 inches wide, this belt fits wide-platen and drum-type finishing machines common in metal fabrication and industrial polishing environments. It is installed and used by metalworkers, fabricators, and finishing technicians.

This belt is suited for light-pressure finishing operations on metal substrates prior to plating or buffing. The flexible JE-weight rayon backing conforms to contoured and flat surfaces, making it appropriate for both manual finishing equipment and automated or robotic belt-finishing systems. It is particularly effective where process consistency and surface finish repeatability are critical across production runs. A grinding aid is incorporated into the construction to reduce heat buildup, helping prevent heat-related warping and discoloration of workpieces.

Key Features

• Microreplicated aluminum oxide pyramids continuously expose fresh mineral as they wear, delivering a consistent cut throughout belt life
• JE-weight rayon cloth backing flexes over contoured surfaces for uniform contact and consistent finishing
• Grinding aid reduces heat buildup, minimizing risk of workpiece warping or discoloration
• Suitable for robotic and automated finishing applications due to predictable, repeatable performance
• Designed for intermediate finishing and fine polishing prior to plating or buffing operations
• Produces finer finishes than conventional coated abrasive belts at equivalent grit designations

Compatibility

Designed for use on belt-finishing machines that accept a 132-inch by 3-inch abrasive belt; suitable for metal fabrication, polishing, and robotic finishing applications requiring consistent surface finish results.

Installation Notes

Install and replace abrasive belts only with the machine powered down and all moving parts at a full stop. Verify belt tracking and tension according to the equipment manufacturer's guidelines before resuming operation. Wear appropriate personal protective equipment, including eye protection and gloves, when handling or changing belts. Inspect the belt for tears or edge damage before each use and remove from service if defects are found.
