3M 7000120732 Surface Conditioning Belt 132x3 Inch Ao

Product Description

The 3M 7000120732 is a non-woven surface conditioning belt designed for metalworking and finishing operations where controlled material removal is required without damaging the workpiece. Built on a durable polyester scrim backing, this belt offers moderate strength and low stretch, making it well suited for consistent surface finishing passes. The aluminum oxide mineral construction paired with a resin bond delivers repeatable cutting action across a range of metal substrates. The open-web nylon fiber structure resists loading, extending usable abrasive life during production runs. Metal fabricators and industrial finishing technicians are the primary installers of this consumable.

This belt is used in surface conditioning sequences where the goal is finishing, blending, or light stock removal without altering part geometry. The springy non-woven nylon construction conforms to contoured surfaces while maintaining consistent contact across flat workpieces. It is appropriate for use on stainless steel, brass, aluminum, and similar metal substrates. Applications include weld blending, surface prep before coating, and general deburring in fabrication and maintenance environments. The belt measures 132 inches in length and 3 inches in width, fitting standard wide-belt and stroke-sander configurations of that dimension.

Key Features

Compatibility

Designed for use on belt sanders and surface conditioning equipment accepting a 132-inch by 3-inch belt. Suitable for metalworking applications on stainless steel, brass, aluminum, and similar substrates.

Installation Notes

Mounting this belt is typically performed by a metal fabricator or machine operator servicing a belt sander or wide-belt finishing machine. Power down and lockout the machine before replacing any abrasive belt. Verify belt tracking alignment after installation and before resuming operation. Follow the equipment manufacturer guidelines for tensioning and guard reinstallation prior to use.
