Norton 66261090276 Abrasive Belt 50 Grit 3x79 in Ceramic

Product Description

The NORTON 66261090276 is a coated abrasive belt engineered for aggressive material removal in industrial and trade grinding applications. Built on a heavyweight Y-weight polyester backing, this belt measures 3 inches wide by 79 inches long and runs a 50-grit ceramic alumina abrasive grain in a closed-coat configuration. The ceramic alumina grain self-sharpens under pressure, maintaining cut rate longer than conventional aluminum oxide belts. At 0.56 pounds per unit, it is suited for stationary belt grinders and wide-contact grinding machines found in fabrication shops, maintenance facilities, and metalworking environments.

This belt is designed for coarse-grade stock removal on metal, weld seams, and hard materials where fast cut and extended belt life are priorities. The R980P series uses a closed-coat layout that maximizes grain density across the full 3-inch by 79-inch surface. Wet or dry operation is supported, giving operators flexibility depending on their grinding setup and workpiece requirements. The Y-weight polyester backing resists stretching and heat buildup during sustained contact grinding.

Key Features

• Ceramic alumina grain self-sharpens under load for sustained cut rate
• Closed-coat construction maximizes abrasive coverage across belt surface
• Y-weight polyester backing provides high tensile strength and heat resistance
• Supports both wet and dry grinding operations
• 50 grit coarse grade suited for rapid stock removal and weld blending
• R980P series design for demanding industrial belt grinding applications

Compatibility

Designed as a replacement-style abrasive belt for stationary belt grinders and combination grinding machines that accept a 3-inch by 79-inch belt configuration.

Installation Notes

Installation should be performed by a qualified operator following the grinder manufacturer's belt-change procedure. Power down and lock out the grinder before removing the worn belt or installing a new one. Confirm belt tracking direction matches the arrow printed on the belt backing before operating. Inspect the contact wheel, platen, and idler for wear or damage before mounting a new belt.
