3M 7000120301 Abrasive Belt 132 Inch Ao Rayon Cloth

Product Description

The 3M 7000120301 is a Trizact 307EA coated abrasive belt built around 3M proprietary microreplication technology. Micron-graded aluminum oxide mineral is formed into uniform three-dimensional pyramids and bonded to a flexible rayon cloth backing. As the pyramids wear during use, fresh sharp cutting edges are continuously exposed, maintaining a consistent cut rate and predictable surface finish throughout the belt's service life. The belt measures 132 inches in length and 3 inches in width. It is intended for intermediate finishing and fine polishing operations in industrial and fabrication environments.

This belt is suited for metalworking applications where controlled, repeatable surface finish is required prior to plating, buffing, or final inspection. The flexible rayon cloth backing conforms to contoured and irregular workpiece geometry, making it practical for both flat and shaped surfaces. Its three-dimensional abrasive structure makes it particularly well-suited for robotic or automated finishing lines where consistent finish across long production runs is critical. Manual grinding and finishing operations also benefit from the belt's self-sharpening characteristics and cooler running behavior compared to conventional coated abrasives.

Key Features

• Microreplication technology forms aluminum oxide into uniform abrasive pyramids for consistent cut and finish
• Self-sharpening pyramid structure continuously exposes fresh mineral as the belt wears
• Runs cooler than conventional abrasives, reducing heat-related workpiece distortion
• Flexible rayon cloth backing conforms to contoured surfaces
• Produces finer finishes than conventional electrostatically coated abrasive belts
• Three-dimensional abrasive design delivers consistent results in robotic finishing applications

Compatibility

Designed for use on belt grinders and finishing machines that accept 132 inch by 3 inch abrasive belts. Appropriate for ferrous and non-ferrous metal finishing prior to plating or buffing operations.

Installation Notes

Installation should be performed by qualified operators familiar with abrasive belt equipment. Power down and lockout the machine before mounting or removing the belt. Confirm belt tracking and tension per the equipment manufacturer guidelines before resuming operation. Inspect the belt for tears or edge damage prior to each use.
