3M 7010326329 Trizact 217EA Abrasive Belt 118x4 Inch Ao

Product Description

The 3M 7010326329 is a Trizact 217EA abrasive belt engineered for intermediate finishing and fine polishing applications in metalworking and fabrication environments. It uses proprietary 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 gradually wear during use, fresh, sharp mineral is continuously exposed, delivering a consistent cut rate and predictable finish throughout the life of the belt. The belt measures 118 inches in length and 4 inches in width. It is primarily used by metal finishing professionals, fabricators, and robotic finishing cell operators.

This belt is suited for intermediate cut-down and fine polishing steps on metal components before plating, buffing, or surface coating. Its flexible JE-weight rayon backing conforms to contoured and irregular surfaces, maintaining contact and consistent abrasion across complex geometry. It performs well under light pressure conditions and is a strong candidate for robotic and automated finishing applications where repeatable results and long abrasive life are required. A built-in grinding aid helps manage heat buildup during extended runs, reducing the risk of heat-related warping or discoloration on workpieces.

Key Features

• Microreplicated aluminum oxide pyramids continuously expose fresh mineral as they wear, sustaining cut rate throughout belt life
• JE-weight rayon cloth backing provides flexibility for finishing contoured and complex surfaces
• Consistent finish quality makes this belt well suited for robotic and automated finishing applications
• Designed for intermediate finishing and fine polishing prior to plating or buffing operations
• Performs at light pressure, allowing the abrasive structure to break down progressively for controlled, repeatable finishes
• Grinding aid reduces heat buildup, helping prevent workpiece warping and surface discoloration

Compatibility

Designed as a replacement-style abrasive belt for belt grinders and finishing machines accepting a 118-inch by 4-inch belt in metalworking, fabrication, and automated finishing applications.

Installation Notes

Abrasive belts of this size are typically mounted and tensioned by metalworking professionals or maintenance technicians on belt grinders or wide-belt finishing machines. Disconnect and lock out power to the machine before changing belts. Verify belt tracking and tension per the machine manufacturer's specifications before resuming operation. Confirm belt direction of travel arrow, if present, matches the machine drive direction.
