Product Overview
The Spiral Brush is manufactured by forming a metal channel strip brush into a continuous helical coil. Unlike a single ring brush, the strip extends through multiple turns, allowing the brush to cover a longer working area while the coil pitch can be adjusted according to the required contact pattern.
Two basic configurations are available. An inverted spiral brush has bristles facing inward toward the center of the coil, creating continuous brushing contact around rods, shafts, wires, tubes and other cylindrical components. An external spiral brush has bristles facing outward and can be installed over a shaft or core to create a cylindrical brushing surface similar to a roller brush.
The coil can be manufactured with different diameters, lengths, pitches and winding directions, while filament materials and metal backing can be selected according to the application. This construction makes spiral brushes suitable for applications ranging from cleaning and wiping to surface treatment, guiding and material handling.
Product Features
- Inverted or External Bristle Orientation – Inverted spiral brushes have inward-facing bristles for contact around rods, shafts, wires and tubes, while external spiral brushes have outward-facing bristles for cleaning or processing external surfaces.
- Adjustable Spiral Pitch – The spacing between each coil can be customized. A close or zero-pitch construction creates a dense brushing surface, while a wider pitch provides separated contact along the working length.
- Left-Hand or Right-Hand Winding – The spiral can be wound in either direction according to the equipment layout, material movement or required brushing action.
- Custom Diameter and Length – Inside diameter, outside diameter and overall coil length can be manufactured according to the installation dimensions.
- Multiple Filament Materials – Nylon, polypropylene, steel wire, stainless steel wire, animal hair and Tampico fiber are available for different cleaning, surface-contact and processing requirements.
- Optional Shaft Assembly – External spiral brushes can be supplied as a loose coil or assembled onto a shaft or core to form a complete cylindrical brush unit.

Applications
The application of a spiral brush depends mainly on whether the bristles face inward or outward. The continuous coil construction allows the brushing area and contact pattern to be adapted by changing the diameter, pitch and overall length.
- Rod, Shaft and Wire Processing – Inverted spiral brushes surround cylindrical components with inward-facing bristles for cleaning, wiping, polishing or surface contact as the workpiece passes through the brush.
- Tube and Cylindrical Component Cleaning – Inside spiral configurations can provide brushing contact around the outside surface of tubes and other round products during continuous processing.
- Surface Cleaning and Finishing – External spiral brushes can be mounted on a shaft or core to create a cylindrical brushing surface for cleaning, wiping and surface treatment.
- Material Guiding and Handling – The spiral arrangement can provide continuous or spaced brush contact for guiding, supporting or moving products through industrial equipment.
- Custom Machinery – Diameter, pitch, winding direction and working length can be adapted to automated production and processing equipment.
Frequently Asked Questions
What is the difference between an inverted spiral brush and an external spiral brush?
An inverted spiral brush has bristles facing inward toward the center of the coil, allowing the brush to surround rods, shafts, wires and other cylindrical components. An external spiral brush has outward-facing bristles and can be mounted on a shaft or core to create a cylindrical brushing surface.
How does spiral pitch affect the brush?
Spiral pitch determines the spacing between adjacent coils. A smaller pitch creates denser and more continuous brush contact, while a larger pitch creates separated contact along the working length. Zero-pitch configurations are also available when a densely packed brushing surface is required.
Can you manufacture left-hand and right-hand spiral brushes?
Yes. Spiral brushes can be manufactured with either left-hand or right-hand winding according to the equipment layout, direction of movement and application requirements.
What information is required for a custom spiral brush?
Please provide the required inside or outside diameter, overall coil length, spiral pitch, bristle orientation, winding direction, filament material and quantity. A drawing, photo or existing sample is also helpful for confirming the brush construction.
