3M 7100020268 Abrasive Belt 168x4 Inch Ao Cloth Gray

Product Description

The 3M 7100020268 is a Trizact 237AA coated abrasive belt designed for intermediate finishing and fine polishing in demanding industrial applications. It uses 3M microreplication technology, where micron-graded aluminum oxide mineral is formed into structured pyramids on an X-weight cloth backing. As the pyramids wear down, fresh sharp mineral is continuously exposed, delivering a consistent cut rate and a predictable fine finish across the full life of the belt. At 168 inches long and 4 inches wide, this belt is sized for wide-platen and large-component grinding setups common in fabrication and finishing shops.

This belt is well suited for ferrous and non-ferrous metal finishing operations where a controlled, repeatable surface finish is required before plating, buffing, or final inspection. The structured abrasive pyramid design makes it particularly effective in robotic and automated finishing lines, where consistent cut and finish uniformity across high part volumes are critical. Manual and semi-automated belt grinding applications also benefit from the cooler-running pyramid structure, which reduces heat buildup and helps prevent workpiece discoloration or warping.

Key Features

• Microreplication technology forms aluminum oxide into structured pyramids for self-sharpening abrasive action
• Continuously exposes fresh mineral as pyramids wear, maintaining consistent cut and finish throughout belt life
• Runs cooler than conventional coated abrasives, reducing heat-related workpiece damage
• Flexible X-weight cloth backing conforms to contours for even finish on complex geometries
• Three-dimensional abrasive structure delivers uniform finishes in robotic and automated applications
• Produces finer surface finishes than conventional electrostatically coated abrasive belts

Compatibility

Designed for use on belt grinders and finishing machines that accept 168-inch by 4-inch abrasive belts. Confirm machine drive and idler roll spacing before installation.

Installation Notes

Installation should be performed by a qualified operator familiar with belt grinding equipment. Power down and lock out the machine before changing belts. Verify belt tracking and tension according to the equipment manufacturer specifications before resuming operation. Inspect the belt for tears or delamination prior to each use.
