3M 7000028336 Trizact 237AA Abrasive Belt 15.5x3.5 in

Product Description

The 3M 7000028336 is a Trizact 237AA coated abrasive belt designed for intermediate finishing and fine polishing applications. It uses 3M microreplication technology in which micron-graded aluminum oxide mineral is formed into three-dimensional pyramids and bonded to an X-weight cloth backing. As the pyramids wear during use, fresh cutting edges are continuously exposed, producing a consistent cut rate and a predictable, fine surface finish throughout the life of the belt. At 15.5 inches long and 3.5 inches wide, this belt fits a range of industrial and production belt sanders used by metalworking fabricators, surface finishing technicians, and toolroom operators.

This belt is suited for intermediate stock removal and fine polishing prior to plating, buffing, or coating operations. The flexible cloth backing conforms to contoured workpiece surfaces, making it effective on both flat and irregular geometries. The three-dimensional abrasive structure delivers repeatable finish consistency, which makes it particularly well-suited to robotic and automated sanding applications where finish uniformity is critical across high production volumes. It performs on ferrous and non-ferrous metals where a fine, controlled finish is required before a downstream surface treatment.

Key Features

• Microreplication technology forms aluminum oxide mineral into self-sharpening pyramids for consistent cut and finish
• Pyramids expose fresh mineral as they wear, maintaining cutting performance throughout belt life
• Flexible X-weight cloth backing conforms to contoured and irregular workpiece surfaces
• Produces finer finishes than conventional electrostatically coated abrasive belts
• Three-dimensional abrasive design delivers repeatable finish results in robotic and automated applications
• Designed for intermediate finishing and fine polishing prior to plating or buffing

Compatibility

Designed as a replacement-style abrasive belt for industrial belt sanders and finishing machines accepting a 15.5 inch by 3.5 inch belt configuration.

Installation Notes

Abrasive belts should be installed by a qualified operator familiar with the sanding or finishing equipment in use. Power down and lockout the machine before changing belts. Confirm belt tracking alignment and tension before resuming operation. Inspect the belt for tears or edge damage before each use and do not run a damaged belt.
