3M 7000139417 Trizact 217EA Abrasive Belt 132x2-1/8 in

Product Description

The 3M 7000139417 is a Trizact 217EA coated abrasive belt designed for intermediate finishing and fine polishing operations on metal surfaces. It uses proprietary microreplication technology in which micron-graded aluminum oxide particles are formed into precise pyramidal structures on a JE-weight rayon cloth backing. As the pyramid tips wear during use, fresh, sharp mineral is continuously exposed, producing a consistent cut rate and predictable surface finish throughout the belt's service life. This belt is well suited for robotic finishing lines and manual applications where repeatable results and long abrasive life are required.

This belt is intended for use on metal finishing applications prior to plating or buffing. Its flexible rayon backing conforms to contoured and irregular surfaces, making it appropriate for both flat stock and shaped components. The grinding aid built into the abrasive compound helps dissipate heat during cut, reducing the risk of thermal warping or discoloration on heat-sensitive workpieces. Metalworking shops, fabrication facilities, and automated finishing lines are the primary installation environments for this belt.

Key Features

• Microreplicated aluminum oxide pyramids continuously expose fresh mineral as they wear, maintaining consistent cut throughout belt life
• JE-weight rayon cloth backing provides flexibility over contoured and irregular surfaces
• Grinding aid reduces heat buildup, helping prevent warping and discoloration of workpieces
• Produces finer surface finishes than conventional coated abrasive belts
• Consistent performance profile makes this belt well suited for robotic and automated finishing applications
• Designed for light-pressure finishing and fine polishing prior to plating or buffing

Compatibility

Designed as a replacement-style abrasive belt for belt grinders and finishing machines accepting a 132-inch by 2-1/8-inch belt in metalworking and industrial finishing applications.

Installation Notes

Installation should be performed by a qualified machine operator or metalworking technician familiar with belt grinder equipment. Power down and de-energize the finishing machine before changing belts. Verify belt tracking and tensioning per the equipment manufacturer's guidelines before resuming operation. Inspect the belt for tears or edge damage before use.
