If you currently use an industrial brush, we can replace it to your specifications or re-engineer
it to address a problem and/or improve performance. We also design custom engineered brushes as solutions for new applications. To help support and enhance
our customers' productivity, we also offer a number of ancillary services.
We appreciate your interest. If you don't find the answer you're seeking in the information provided here, please contact us.
Whether you're cleaning, dusting, or polishing…doing prep work or finish… moving material to, through or from a process…in a cleanroom, factory or field …chances are we've been there too.

Your evaluation of brush performance is based how effectively the brush meets the standards you set…for your application…in your process conditions…and
within your budget.
That's why it's so important to gather information about your situation and needs before suggesting a brush solution. It's also
important to understand that you can change the combination of features to address the various considerations (brush cost, brush performance, brush
conditions, etc.). We want to help you prioritize those issues to ensure the brush you select provides the best performance for the best value.
A brief look at some common brush problems helps illustrate the value of this approach.
Brush "Chatter" or Vibration
Brush chatter occurs when a brush vibrates, or jumps up and down on the surface rather than maintain a smooth, consistent down pressure. The result is an
oscillating pattern across the brushed surface.
With greater downward pressure, the brush may mar the material surface; as the brush lifts up, it may not provide adequate cleaning pressure.
In addition, as the vibration becomes more serious, it can damage other parts of the equipment (e.g., excessive wear
causes bearings to wear out more quickly). Brush chatter is often caused by a brush that is not in balance. To help avoid this, United Rotary Bush offers
a rigorous pre-balance test of your brush shaft and precision dynamic balancing of the finished brush roll. Brush chatter can also be caused by worn
bearings or other equipment problems.
Brush Streaks and Surface Marking
There are a number of reasons why a brush will leave streaks or other marks on the brushed surface. For example, the brush may not be operating at the
optimal speed or downward pressure for your particular application or in your specific sweeping conditions. There may be issues with your brush design
operating. You may need to use a more or less agressive filament. Or perhaps increase the brush density. At United Rotary Brush, you can work with
professional brush consultants who offer an in-depth knowledge of brush materials as well as years of experience addressing brush performance issues
across a range of applications.
"Shedding" or loss of filament is the most common type of brush failure. Not only does this diminish brush performance and life, it may create process down
time and increase costs. Filament breakage may occur if the filament material is not optimal for the application conditions. The type, diameter or trim
length of the filament may need to be adjusted. Excess heat will accelerate brush failure. Proper cooling is required to maintian optimal perfect life.
The type of construction of your brush may be another issue, depending on your current brush settings or speed as well as process conditions (wet/dry;
hot/cold; etc.). With a custom engineered brush, you can select the best core or channel components, choose the optimal filament material, and pick the
construction that provides your best level of protection against brush failure.
What kind of brush offers you the best performance at the best value? That can involve a number of variables. These issues are inter-related, but can be considered in four broad categories:
- Rewrapped shaft
- Disposable brush
- Brush Strips
- OD/ID (filament trim lengthZ)
- Brush face
- Metal Channel
- Brush Core
- Brush speed (rpm)
- Downward pressure
How these variables are combined will depend upon your operation. United Rotary Brush custom brush design specialists will work with you to answer
three fundamental questions:
- Are there changes to your brush design that could help increase line speed or other production enhancement?
- Are there changes to your brush design that could help increase the life of your brush?
- Are there changes to your brush design that could help you cut brush costs without making significant sacrifice to your process outputs?
Please contact us to give one of our custom brush specialists an opportunity to help you improve your operation.
Will a rewrapable or disposable brush work best for you?
When your process demands the most effective brushing, United Rotary Brush rewrapable brushes provide the solution. Our brushes are wound directly on
your shaft and are dynamically balanced to ensure smooth, uniform brushing for the most critical surfaces. After the brush life is consumed simply
return the worn brush shaft to our facility to be rewrapped.
In some cases, a disposable brush provides a quicker, more convenient replacement solution. These brushes are designed to be disposed of once the
filament is worn out. Benefits of disposable brushes are:
- Quicker change out and replacement.
- No need to send shafts back to rewraping.
- Easy to store and maintain spares.
Brush strips and coils are available in a wide range of sizes and configurations. They offer a low cost alternative for light duty applications.
Materials of Brush Construction - Brush Filament
Due to the chemical composition of the different filament materials, some filament varieties are better suited for certain applications than others.
In addition, filament specifications – diameter, trim length, and grit size – can be specified to meet the needs of your application.
Following is a brief overview of some of the primary brush filament options:
Nylon is a very common filament choice because of its range of use. It can be formulated to provide heat, chemical and abrasion resistance, and features
excellent flex life, bend recovery, and "Flick Action."
Abrasive Nylon is required for aggressive cleaning or demanding processing applications. The nylon is impregnated with Aluminum Oxide or Silicone
Carbide grit. Like sand paper, the grit size can be adjusted to meet the application requirements.
Polypropylene is a common economical synthetic filament that is formulated to address a wide range of brushing applications. Polypropylene is
particularly applicable for high moisture conditions where consistent bristle stiffness is required and also offers resistance to many acids and solvents.
Polyester is a synthetic filament used often on trommel screen and harvesting brushes. It offers a consistant stiffness in wet applications and
Natural filaments, such as Tampico or other plant fiber, are less abrasive than synthetic materials and often appropriate for wet cleaning conditions.
Wire is a common filament choice, especially in situations in which a "cutting action" is required. Wire can be drawn from various metals – including
stainless steel, carbon steel and brass – depending upon the requirements of the application.
Your United Rotary Brush custom brush specialist can help you choose the best filament for your application and operating conditions.
United Rotary Brush will work with you to develop a program to meet your unique needs.
