Norton 69957307358 Abrasive Belt 120 Grit 37x75 in Zirconia

Product Description

The NORTON 69957307358 is a coated abrasive belt designed for heavy-duty grinding and finishing applications. Part of the R823P Series, this belt measures 37 inches wide by 75 inches long and runs a 120-grit medium-grade cutting surface of zirconia alumina. Zirconia alumina is a self-sharpening abrasive grain well suited to aggressive stock removal on metals, weld seams, and fabricated components. The polyester cloth backing carries an X-weight designation, indicating a stiff, durable substrate that resists tearing under high-pressure contact. Closed-coat density maximizes abrasive coverage across the full belt face. The belt supports both wet and dry operation.

This belt is intended for use on wide belt sanders and large-format grinding machines found in metal fabrication shops, structural steel operations, and industrial production environments. At 37 by 75 inches, it fits large-platen or drum-driven belt machines common in high-volume deburring, surface conditioning, and weld-blending work. Fabricators, metal finishers, and maintenance machinists are the primary installers and operators. The 120-grit rating positions it in the medium-finishing range, useful for blending after coarser stock-removal passes or for achieving a consistent scratch pattern before final finishing steps.

Key Features

• Zirconia alumina grain self-sharpens during use, extending belt life on ferrous and hard metals
• X-weight polyester cloth backing provides stiffness and tear resistance under high-contact-pressure conditions
• Closed-coat construction maximizes abrasive grain density for efficient material removal
• 120-grit medium grade balances stock removal with surface finish quality
• Rated for both wet and dry operation, compatible with coolant-assisted grinding setups
• R823P Series construction is consistent with industrial production and fabrication demands

Compatibility

Designed for wide belt sanders and large-format abrasive belt machines that accept a 37-inch by 75-inch belt. Verify machine contact drum or platen dimensions and belt-tracking specifications before mounting.

Installation Notes

Belt installation and replacement should be performed by a qualified operator following the machine manufacturer's procedures. Power down and lockout/tagout the machine before changing belts. Inspect the contact drum or platen for wear or damage prior to mounting a new belt. Confirm belt tracking alignment before resuming operation to prevent edge damage or belt failure.
