3M 7010364845 Trizact 217EA Abrasive Belt 132x3 Inch Ao

Product Description

The 3M 7010364845 is a Trizact 217EA coated abrasive belt designed for intermediate finishing and fine polishing applications. It uses proprietary microreplication technology in which micron-graded aluminum oxide particles are formed into tiny pyramids and bonded to a JE-weight rayon cloth backing. As the pyramids wear down during use, fresh, sharp mineral is continuously exposed. This produces a consistent cut rate and a predictable, fine surface finish throughout the entire life of the belt. The belt measures 132 inches in length and 3 inches in width. It is installed on stationary or automated belt grinding equipment by abrasive finishing technicians and production metalworking personnel.

This belt is suited for intermediate finishing and fine polishing on metal workpieces prior to plating or buffing operations. The flexible JE-weight rayon cloth backing conforms to contoured and irregular surfaces, making it effective on complex part geometries. Its consistent performance and extended abrasive life make it a reliable choice for robotic and automated finishing cells where repeatable results are required. It is optimized for light-pressure applications where controlled mineral breakdown is needed to maintain cut and produce uniform surface finishes.

Key Features

• Microreplicated aluminum oxide pyramids continuously expose fresh mineral as they wear, maintaining consistent cut throughout belt life
• Flexible JE-weight rayon cloth backing conforms to contoured surfaces for uniform finishing
• Produces finer finishes than conventional coated abrasive belts
• Grinding aid integrated into construction helps prevent heat-related warping and discoloration of workpieces
• Consistent performance profile makes this belt well suited for robotic and automated finishing applications
• Designed for light-pressure use in intermediate finishing and pre-plate or pre-buff polishing sequences

Compatibility

Designed as a direct-fit replacement abrasive belt for belt grinding and finishing machines that accept 132-inch by 3-inch endless abrasive belts.

Installation Notes

Installation should be performed by qualified abrasive finishing or metalworking personnel following the machine manufacturer's belt-change procedures. Power down and de-energize the belt grinder completely before removing the worn belt or installing a new one. Confirm belt tracking direction arrow aligns with the machine's drive roll rotation before resuming operation. Inspect the contact wheel, platen, and idler roll for wear or damage each time the belt is changed.
