Rotary brushes, also referred to as cylinder or coil brushes, are manufactured by Tanis in both a coiled metal back strip construction and a stapled set construction. Our product offering includes our specially designed conveyor brushes as well as our custom designed rotary brushes for specific application or size specification needs.

The metal back construction can be wound as loose or free coil for mounting on your existing equipment or we can coil and assemble the rotary brush directly onto a shaft designed specifically for you. We offer eight metal back sizes and various length, filament type and core material options. We also provide rotary brush refurbishing for coiled metal back strip brushes as a value-added service to extend your investment and ensure consistent high quality performance. Our stapled set machining capabilities allow us to offer more versatility in rotary brush specifications and limitless stapled set configurations and patterns.

Product Scope

Rotary brushes or cylinder brushes are manufactured using either a coiled metal back strip construction or a stapled set construction. The coiled metal back strip brushes are ideal for applications that require constant brush contact and pressure, where as stapled set brushes are ideal for applications requiring more versatility in design and shape.

Rotary Brushes Construction

Metal Back Strip Rotary Brushes

Construction

Coiled metal back strip brushes are manufactured by winding a straight metal back strip brush around a core construction. The metal back strip brush consists of densely compressed filament laid into an unformed metal strip which is formed vertically into a “U” shape by a binding wire.

The strips are coiled close wound under pressure to produce a dense brush face or open wound for less density. A larger winding pitch provides a less dense brush and conforms better to the surface being brushed. Once the coil is finished, Tanis can then assemble it to a core, a shaft or supply it unassembled for mounting on installed equipment.

Standard Core Systems

  • Solid stainless steel or steel shaft with journal ends machined to your requirements. Recommended shaft sizes between 1/2” to 2”. Due to weight of the final assembly, we recommend shaft sizes not to exceed 2” diameter.
  • Stainless steel or steel tubing is used for the core. Journal ends for drive and bearing surfaces are press fit and shrunk inside the tube. The journal ends are either stainless steel or steel.
  • Stainless steel or steel tube with end collars to accept customers’ shaft size. Tube diameter can be made to any size. Collars are made with set screws and/or single or double keyways. Design is recommended for slower speed applications.

Stapled Set Rotary Brushes

Stapled set rotary and wheel brushes are manufactured by inserting individual tufts of filament into a drilled hole in a block of plastic and securing with a staple. The staple is made of steel or nickel-silver which is predicated by the environment and the conditions the brush will be performing under.

Core Construction

Stapled set rotary brushes are made with an extruded or machined plastic core pressed onto a shaft or core. The core can either be press fit onto a shaft, an internal tube with collars to accept an installed shaft, or a tube construction with journal ends. Plastics including polyvinylchloride (PVC), polypropylene, high-density polyethylene (HDPE), ultra-high molecular weight (UHMW), ABS or delrin are used as core materials.

Tanis also features a bonded core technology casting urethane material onto a shaft as another core construction for stapled rotary brushes. The urethane is cast directly to the metal shaft.

Stapled set wheel brushes are made with a round, plastic block including an arbor hole. Bearings can be press fit into the arbor hole, if required.

The Standard Core Systems are:

Core

 

  1. Solid stainless steel or steel shaft with journal ends machined to your requirements. Recommended shaft sizes between 1/2” to 2”. Due to weight of the final assembly, we recommend shaft sizes not to exceed 2” diameter.
  2. Stainless steel or steel tubing is used for the core. Journal ends for drive and bearing surfaces are press fit and shrunk inside the tube. The journal ends are either stainless steel or steel.
  3. Stainless steel or steel tube with end collars to accept customers’ shaft size. Tube diameter can be made to any size. Collars are made with set screws and/or single or double keyways. Design is recommended for slower speed applications.
  4. Stainless steel or steel tubing with flange mounted journal ends for drive and bearing surfaces. Tube diameters usually range from 4” to 12”. This design used for long shaft ends for better support. The ends are either shrunk in place or connected by screws for permanent fit.

Rotary Brushes Design Specifications

Coil Wound Rotary Brushes

Coil Wound

Tanis has eight standard backing sizes for our metal back strip brushes – #2 ½ , #3, #4, #5, #7, #8, #10, #16 – ranging from .114” high x .098” wide to .688” high x .624” wide. The standard

backing materials include galvanized and stainless steel. Brass and aluminum backing can be available upon request. For special sizes and tolerances, please contact our technical sales and engineering staff.

Tanis can assemble coil wound rotary brushes to a core, a shaft or supply the coil unassembled for mounting on installed equipment. The shafts can be machined to customer specifications and core diameters with few design limitations, however weight can be a factor in the final assembly. Since most coils are welded directly to a tube or shaft, end rings can be machined for a better cosmetic appearance. If a more economical finish is desired, we can leave the weld and channel exposed.

We offer refurbishing services for coil wound rotary brushes on an existing shaft or tube by removing the worn brush and refilling the shaft or tube with a new coil wound brush. Tanis can also repair journal or stub ends on shafts to provide a new surface for drive side and bearings.

Stapled Set Rotary Brushes

Stapled set rotary and wheel brushes are manufactured by inserting individual tufts of filament into a drilled hole in a block of plastic and securing with a staple. The staple is made of steel or nickel-silver which is predicated by the environment and the conditions the brush will be performing under.

Hole Pattern and Design

Stapled Rotary Brush Patterns

Using the latest in machining technology, the stapled set wheel or rotary brushes can be designed and manufactured in virtually any hole or tuft patterns to produce a desired density and brush pattern. Standard patterns include straight, staggered, spiral (helical) and chevron (herringbone) patterns. A spiral or herringbone pattern is used to orient product in a specific direction or to give a specific brushing effect.

Generally, the tuft holes are drilled and filled vertically but depending on the application, the hole can be drilled and the filament inserted at an angle. The brush filament is trimmed in the final processing stage to provide a consistent, uniform brush face.

Rotary Brushes Fill Material

We can manufacture rotary brushes using any of our available synthetic, natural or wire filaments. The type of material selected will depend upon the desired characteristics. Fill may be stiff or soft, thick or thin, repel or absorb water, chemical or heat resistant, flexible to a greater or lesser extent, and resistant to bending or abrasion.

Other filament characteristics include brush density and bristle length. Choosing a crimped filament instead of a level or straight filament will provide you with a more dense brush appearance and a continuous, more even brushing action. The crimp is measured by amplitude, depth of the crimp, frequency and number of crimps per inch. Level or straight bristles provide a lesser brush density appearance. The measurement of the exposed filament is known as the trim length and is the working strength of the brush.

The last filament characteristic is the finished trim; choices include:

  • Flat trim is the most common finished trim providing a consistent, uniform brush face.
  • Tapered trim is common in applications to accommodate deflection on a surface.
  • Step trim is used for brushing irregular or uneven surfaces.

Brush Repair

Tanis can repair and refurbish used or worn coil wound rotary/cylinder and hand drawn brushes, saving time and money by eliminating the need for a new block, core or shaft construction. Refurbishing can be done multiple times on brushes with a core or shaft construction that is in good condition. We also work to extend the life of the original core and provide additional cost savings by adding durability with a heavier tube wall or solid shaft.

Coil Wound Rotary Brush Repair

To refurbish a coil wound rotary brush on an existing shaft, we remove the worn brush, clean the core and refill it with a new brush. The brush is refilled using the same machining techniques as the original brush, at considerable cost savings. Tanis can also repair journal or stub ends on shafts to provide a new surface for drives and bearings.

Hand Drawn Brush Repair

Hand drawn brushes are a variation of stapled set brushes, but are unique in that the fill material is hand sewn into a metal, wood or plastic block with wire or a nylon cord. The original block or split round core is typically made of steel, aluminum, brass and occasionally wood, plastic, leather or urethane. To refurbish these brushes we cut loose the hand drawn wire, pull out and remove the old fill material and refill with new filament in the original block.
