Product Positioning

Heavy-Duty Sanding Belts Beyond Standard Aluminum Oxide

Zirconia sanding belts are industrial belts designed for high load and high stock removal applications, offering a performance upgrade over standard aluminum oxide belts where efficiency and durability are critical.

Product Overview

Self-Sharpening Grain and Extended Belt Life

Zirconia abrasives feature a microcrystalline structure that continuously fractures under pressure to expose new cutting edges, creating a self-sharpening effect.
This allows the belt to maintain aggressive cutting performance under heavy loads while significantly extending usable life.

High Load Application Engineering

Designed for Pressure, Speed and Material Removal

Zirconia belts perform best under high contact pressure, heavy feed rates, and elevated belt speeds, making them ideal for continuous heavy grinding processes.

• Effective for large material removal
• Performs well under high feed pressure
• Outperforms aluminum oxide belts in heavy-load conditions

Backing Selection & Tension Compatibility

Ensuring Structural Stability Under Heavy Loads

X-weight cloth backing: Suitable for medium to high tension machines

Y-weight cloth backing: Designed for high-tension wide belt sanders

Backing strength is critical for preventing belt failure under heavy load conditions.

Tension, Speed & Self-Sharpening

Activating Zirconia Performance

Zirconia self-sharpening requires sufficient pressure and speed to activate:

• Low tension: Insufficient self-sharpening
• Low pressure: Grain polishing instead of fracturing
• Proper load: Continuous sharp cutting
