3M 7000148226 Trizact 217EA Abrasive Belt 168x3 Inch Ao

Product Description

The 3M 7000148226 is a Trizact 217EA coated abrasive belt designed for intermediate finishing and fine polishing on metal and other hard surfaces. It uses 3M microreplication technology in which micron-graded aluminum oxide particles are formed into precisely shaped pyramids and bonded to a JE-weight rayon cloth backing. As the pyramids wear during use, fresh abrasive mineral is continuously exposed, delivering a consistent cut rate and a predictable surface finish from start to finish. The belt measures 168 inches in length and 3 inches in width. It is typically installed and operated by metalworkers, fabricators, and finishing technicians in production and job-shop environments.

This belt is suited for intermediate finishing and fine polishing steps prior to plating or buffing operations. The flexible JE-weight rayon backing conforms to contoured and irregular surfaces, making it effective for parts with complex geometry. Its consistent cut rate and long abrasive life also make it well suited for automated and robotic belt-finishing applications where repeatability is critical. It is intended for light-pressure applications where controlled material removal and surface consistency are the primary objectives.

Key Features

• Microreplicated aluminum oxide pyramids continuously expose fresh mineral for consistent cut throughout belt life
• Flexible JE-weight rayon cloth backing conforms to contoured surfaces for uniform finishing
• Consistent performance supports use in robotic and automated finishing applications
• Grinding aid reduces heat buildup, helping prevent warping and discoloration of workpieces
• Produces finer surface finishes than conventional coated abrasive belts
• Suited for light-pressure finishing prior to plating or buffing

Compatibility

Designed as an OEM-style replacement or standard consumable for belt finishing machines and grinders that accept 168-inch by 3-inch abrasive belts.

Installation Notes

Installation should be performed by qualified finishing or machine operators familiar with belt-grinder safety practices. Power down and lock out the machine before mounting or removing the belt. Verify the belt tracking direction arrow aligns with the machine drive direction before startup. Inspect the belt for tears or delamination before each use and do not exceed the machine manufacturer's recommended operating speed.
