Norton 69957328317 Abrasive Belt 80 Grit 36x75 in

Product Description

The NORTON 69957328317 is a heavy-duty coated abrasive belt designed for high-material-removal applications on wide belt sanders and industrial grinding machines. Built on a Y-weight cloth backing for maximum stiffness and durability under load, this belt measures 36 inches wide by 75 inches long and runs at 80 grit, placing it squarely in the medium grade range. The abrasive material is zirconia alumina, a self-sharpening grain that fractures during use to expose fresh cutting edges, sustaining cut rate across the full life of the belt. Open coat density reduces loading when working softer metals or wood composites. Weighing 8.5 pounds, this is a full-production-scale belt suited for fabrication shops, weld prep, and surface conditioning tasks.

This belt is suited for dry-operation wide belt sanding and grinding in industrial and heavy fabrication environments. Typical applications include structural steel preparation, weld seam blending, plate and sheet metal finishing, and large-panel wood or composite stock removal. The R811 series designation identifies the product family within NORTON's coated abrasives line. Fabricators, metalworking shops, millwork operations, and production grinding facilities are the primary end users. The 36-inch width accommodates wide-belt machines common in both metalworking and woodworking production lines.

Key Features

• Zirconia alumina grain self-sharpens during use for sustained cut rate and longer belt life
• 80 grit medium grade balances aggressive stock removal with acceptable surface finish
• Y-weight cloth backing provides high tensile strength and resistance to tearing under heavy feed pressure
• Open coat density minimizes loading and heat buildup, extending usable belt life on softer or gummy materials
• Dry-operation rated for use on standard wide belt sanding and grinding equipment
• 36 x 75 inch dimensions fit full-production wide belt machines in metal and wood fabrication

Compatibility

Designed as a direct-fit replacement or stock belt for industrial wide belt sanding and grinding machines accepting a 36 x 75 inch coated abrasive belt in dry-operation service.

Installation Notes

Belt installation and tensioning should be performed by qualified personnel following the machine manufacturer's guidelines. Always power down and lock out the machine before changing belts. Inspect the platen, contact drum, and belt tracking components for wear before mounting a new belt. Ensure the belt is oriented with the arrow or splice direction matching the machine's rotation to prevent splice failure during operation.
