3M 7100138309 Ceramic Abrasive Belt 78.75x17.32 Inch

Product Description

The 3M 7100138309 is a Trizact 953FA abrasive belt engineered for high-performance wet centerless and flat grinding applications. It uses a 3M proprietary ceramic grain structure that delivers fast, aggressive material removal with consistent, repeatable results. The belt is built on an XF-weight cloth backing, which balances durability with the flexibility required for contour and flat surface work. Designed for industrial grinding environments, this belt is typically installed and maintained by machining and grinding equipment operators in precision metalworking settings. It handles ferrous metals, stainless steel, and nonferrous workpieces effectively.

This belt is suited for dimensioning and blending operations in wet centerless or flat grinding setups. Its ceramic grain structure supports higher throughput by extending belt life and reducing the number of belt changes during production runs. The design also reduces operator skill dependency when holding close tolerances and finish specifications, making it a practical alternative to bonded abrasive wheels in qualifying applications. Minimum order quantity is 5 units per purchase.

Key Features

• Proprietary 3M ceramic grain for fast, aggressive cutting action with predictable results
• XF-weight cloth backing provides durability combined with added flexibility
• Consistent part geometry and surface finish across production runs
• Higher throughput potential — fewer belt changes versus conventional abrasives
• Reduces operator skill dependency for maintaining close tolerances and finish specs
• Serves as a direct alternative to bonded abrasive wheels without requiring new equipment investment

Compatibility

Designed for use in wet centerless and flat grinding machines that accept belts measuring 78.75 inches in length and 17.32 inches in width. Suitable for ferrous, stainless steel, and nonferrous workpiece materials.

Installation Notes

Belt installation should be performed by qualified grinding equipment operators following the machine manufacturer's guidelines. Ensure the grinding machine is fully powered down and locked out before changing belts. Confirm belt tracking and tension per machine specifications before resuming wet grinding operations. Always use appropriate personal protective equipment when handling abrasive belts and operating grinding equipment.
