3M 7100074178 Scotch-brite Surface Conditioning Belt 132x6 in

Product Description

The 3M 7100074178 is a Scotch-Brite Surface Conditioning Low Stretch Belt built for metalworking and fabrication applications where consistent surface finishing is required without aggressive stock removal. Measuring 132 inches in length and 6 inches in width, this non-woven belt uses aluminum oxide (AO) mineral bonded with resin to deliver controlled cutting action. The open-web nylon fiber construction resists loading and helps maintain workpiece geometry throughout the finishing pass. It is installed and operated by metalworkers, fabricators, and maintenance technicians working with wide-belt and contact-belt finishing machines.

This belt is suited for surface conditioning tasks on a broad range of substrates including stainless steel and brass. Its moderate durability and flexibility position it between light deburring and aggressive cutting in a multi-step sequence, making it effective for blending, cleaning, and finishing operations in both shop and light industrial environments. The low-stretch polyester scrim backing keeps the belt stable under tension, which is important on wider, longer belt configurations like this one.

Key Features

• Non-woven aluminum oxide construction delivers controlled finishing without marring the substrate
• Durable cloth and polyester scrim backing designed for low-stretch belt applications
• Open web resists loading, extending abrasive service life during continuous use
• Springy nylon fibers maintain workpiece geometry while finishing
• Compatible with a variety of substrates including stainless steel and brass
• Resin bond secures mineral to backing for consistent performance across passes

Compatibility

Designed for use on wide-belt and contact-belt surface conditioning machines that accept 132-inch by 6-inch non-woven abrasive belts.

Installation Notes

Belt installation should be performed by a qualified operator following the machine manufacturer's belt-tracking and tensioning procedures. Power down and de-energize the finishing machine completely before changing belts. Inspect the belt for tears or delamination before mounting. Verify belt arrow direction matches machine rotation before starting the equipment.
