Sanding Belts

Sanding belts are an essential tool for woodworking, metalworking, fabrication, and finishing applications. Designed to provide consistent abrasion, they save time and deliver high-quality results compared to traditional sandpaper. At SAIC, we manufacture and supply custom sanding belts to suit any size, grit, or substrate.

What Are Sanding Belts?

A sanding belt is an abrasive strip joined into a loop and mounted on a belt sander or linisher. They come in different sizes, abrasive grains, and backing materials depending on the job. Choosing the right belt ensures better performance, longer life, and the perfect finish.

Types of Sanding Belts

Different applications require different abrasives. Here are the main types:

Aluminium Oxide Belts

General-purpose belts ideal for wood, soft metals, and composites. Cost-effective, versatile, and available in a wide range of grits.

Zirconia Belts

High-performance abrasive that self-sharpens. Best for stainless steel, carbon steel, and heavy stock removal on hard woods.

Ceramic Belts

Premium belts designed for high-pressure grinding of tough metals. They cut cooler and last longer than zirconia or aluminium oxide.

Silicon Carbide Belts

Sharp and brittle grain that excels on glass, stone, composites, and plastics. Also used for fine finishing and polishing.

Non-Woven SCM Belts

Surface conditioning belts (Coarse, Medium, Very Fine) used for blending, cleaning, and finishing metal surfaces without removing base material.

Trizact Belts

Engineered 3M belts that give a uniform, repeatable finish. Excellent for stainless steel finishing and polishing applications.

Agglomerate Belts

Special long-life abrasives where multiple layers of grit extend the service life of the belt. Useful for continuous grinding operations.

Felt Belts

Non-abrasive belts used with polishing compounds for mirror finishing on metals and plastics.

Choosing the Right Grit

• Coarse grits (24–60): heavy stock removal and shaping
• Medium grits (80–120): general sanding, deburring, and surface prep
• Fine grits (150–400+): finishing and polishing
• SCM grades: Coarse, Medium, and Very Fine for non-woven finishing

FAQs About Sanding Belts

What are sanding belts used for?

Sanding belts are used for grinding, finishing, deburring, and polishing wood, metals, plastics, and composites depending on the abrasive grain.

How do I choose the right sanding belt?

Choose based on material (wood, metal, glass, etc.), required finish, and desired belt life. Our belt calculator helps you select the best option.

Can sanding belts be custom made?

Yes — we manufacture belts to order, in any size, substrate, or grit, ensuring the perfect fit for your machine and application.

How long do sanding belts last?

It depends on substrate and usage. Ceramic and agglomerate belts last longest under heavy use, while aluminium oxide belts are more cost-effective for general sanding.

Can sanding belts be used wet?

Yes, many belts (like silicon carbide and some zirconia) are suitable for wet sanding. Always check the belt type and backing before use.
