Industrial rotary brushes are specifically designed so that the brush filaments rotate around a revolving axis. They are usually mechanically powered or automated for applications such as surface sweeping, automatic material polishing, and cleaning industrial conveyor systems. Rotary brushes are typically available in three designs: cylindrical, wheel-shaped, and cup-shaped brushes.
Types of Industrial Rotary Brushes
At Cocker-Weber Brush Company, we pride ourselves on providing the highest-quality industrial rotary brushes for numerous industries and applications. Our wheel, cylinder, and cup rotary brushes are available in a variety of sizes and materials to suit your unique needs.
As the name implies, wheel rotary brushes consist of a flat wheel with brush filaments placed around the outer edge of the wheel. By definition, the width of the brush surface that contains the filaments must be less than the diameter of the brush. A wheel rotary brush is typically powered by a turning shaft or gear mechanism, depending on the application.
When the width of the filament brush surface is greater than the diameter of the central wheel, the brush is considered a rotary cylinder brush. Easily identified by their cylindrical shape, these brushes are composed of a central tube or bar that is covered on the outside with brush filaments. The core tube can be composed of a broad range of plastics, or even wood, and filaments are available in synthetic, natural, and metal materials. Industrial cylinder brushes are often used to clean conveyor belts, wash produce, polish finished products, and spread coatings such as paint or adhesive.
Cup rotary brushes are similar to wheel brushes, but the filaments of the brush are situated around one lateral edge of the disk instead of the outside edge. The brush filaments are oriented to point in one direction perpendicular to the axis of the wheel, creating a cup shape that leaves the other side of the wheel clear of filaments. Industrial cup rotary brushes are particularly useful for focused cleaning and polishing, and they can often be found on vacuum equipment and drill-powered rotary brushes.
Industrial Rotary Brush Materials
There are numerous synthetic materials available for use in industrial brushes. Nylon and polypropylene are the most common brush materials, as they create filaments that are extremely durable, waterproof, and chemical-resistant. Synthetic filaments are less expensive to manufacture than harvesting natural fibers and metal. They are also antimicrobial and easy to clean, which makes them ideal for food processing and in health care settings.
Metals used in rotary wire brushes include bronze, brass, stainless steel, and carbon steel. Bronze and brass filaments are often used to clean and polish items in applications that require electrical conductivity and corrosion-resistance. Stainless and carbon steels are stronger and used for burnishing and deburring highly durable materials.
Natural fibers for brush filaments are derived from both plant and animal sources, such as boar’s bristles, horse hair, goat hair, Tampico agave plants, bassine, and palmyra. These materials offer a variety of properties: Boar’s bristles, for example, are stiff, but goat’s hair is extremely soft. In general, natural fibers are less harsh on surfaces compared to metal filaments and are often used for delicate and sensitive surfaces. Even soft natural fibers are highly durable.
