3M 7000120731 Scotch-brite Surface Conditioning Belt

Product Description

The 3M 7000120731 is a Scotch-Brite Surface Conditioning Low Stretch Belt designed for metalworking and fabrication applications where controlled material removal is required without marring or distorting the workpiece. Constructed with a durable cloth and polyester scrim backing, this belt resists stretching under load, making it well suited for consistent, repeatable surface finishing passes. The non-woven nylon fiber construction is open-web, which resists loading and extends abrasive service life. Aluminum oxide (AO) mineral bonded with resin provides reliable cut and finish across a moderate range of aggressiveness. At 132 inches long and 3 inches wide, it fits wide-belt and stroke-sander configurations common in metal fab shops.

This belt is used in residential and commercial metal fabrication, maintenance, and surface preparation environments. It performs on a variety of substrates including stainless steel, brass, aluminum, and mild steel. The springy non-woven fiber structure conforms to workpiece geometry, allowing operators to blend welds, remove mill scale, or achieve a consistent finish without changing the dimensional profile of the part. It fits into multi-step finishing sequences where moderate cut without aggressive stock removal is the goal. Fabricators, maintenance techs, and metalworkers are the primary installers and end users.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive belt equipment. Power down and lockout the sander before changing belts. Confirm belt tracking and tension per the machine manufacturer guidelines before resuming operation. Inspect the belt for tears or delamination before each use and do not exceed the machine's rated belt speed.
