3M 7000120296 Trizact Cloth Belt 4x90 in A45

Product Description

The 3M 7000120296 is an aluminum oxide Trizact cloth belt designed for precision grinding and finishing applications. Built on an X-weight cloth backing, it delivers the durability needed for demanding material removal tasks. The belt uses resin bonding for improved heat resistance, and a grinding aid is incorporated into the abrasive structure to promote cooler cutting temperatures during extended use. The A45 grade positions this belt for fine finishing work where surface quality and consistent cut rate both matter. A film media splice construction supports smooth, uninterrupted belt travel during operation.

This belt is suited for metalworking and fabrication environments where consistent surface finish is required. It is commonly used on wide belt sanders and stroke sanders in shop and industrial settings. The 4 inches by 90 inches format fits a range of production-grade belt grinding machines. Skilled tradespeople, machinists, and fabricators working with ferrous and non-ferrous metals will find this belt appropriate for fine stock removal and pre-polish finishing stages.

Key Features

• Aluminum oxide abrasive mineral for consistent cut and long service life
• X-weight cloth backing provides high tensile strength and flexibility
• Resin bond construction resists heat buildup during aggressive grinding
• Grinding aid integrated into abrasive layer for cooler grinding temperatures
• Film media splice for smooth, uninterrupted belt tracking and travel
• A45 grade suited for fine finishing and pre-polish surface preparation

Compatibility

Designed as a replacement-style abrasive belt for production belt grinders and wide belt sanders accepting a 4 inches by 90 inches belt format.

Installation Notes

Belt installation should be performed with the machine fully powered down and locked out per standard OSHA lockout/tagout procedures. Confirm belt tracking direction arrow aligns with machine drive direction before startup. Inspect the platen, contact wheel, and tensioner for wear before mounting a new belt. Allow the belt to run briefly at operating speed before applying workpiece pressure to confirm proper tracking.
