Send Your Brush Roll DrawingWhat Is a Disc-Type Brush Roll?
A disc-type brush roll, also called a disk brush roll or stacked disc brush roll, is a cylindrical brush assembled from individual brush discs along a shaft. Each disc carries outward-facing filament bundles; together, the discs create the working face that contacts the strip or sheet.
In this construction, filaments are secured through holes in metal plates. The plates are stacked and retained to match the required face length, brush density and machine interface.

Brush Discs and Roll Assemblies
Available as individual discs, complete stacks or brush roll assemblies.
Complete disc stacks
Matched sets of brush discs for the required working face length.
Complete brush roll assemblies
Brush discs assembled with a shaft and end fittings to the agreed drawing.
Abrasive Filaments We Provide
We provide nylon filaments containing abrasive particles, arranged in bundles on the metal brush discs.
- Silicon Carbide (SiC) Abrasive Nylon
- Aluminum Oxide Abrasive Nylon
- Ceramic Abrasive Nylon
- Diamond Abrasive Nylon
Common filament diameters: 0.25, 0.3, 0.4, 0.5, 0.6, 0.8, 1.0, 1.2, 1.6 and 2.0 mm.
Abrasive type, grit, filament diameter, nylon grade and trim are selected for the workpiece, required finish and wet or dry conditions.
The binding wire that secures the bundles to the plate is a retaining component; it does not mean the roll uses exposed steel-wire fill.
Review abrasive filament brush rollersApplications in Strip and Sheet Processing
- Steel strip and sheet cleaning before further processing
- Cleaning and surface conditioning at specified pickling-line stations
- Cleaning sections associated with annealing and galvanizing lines
- Polishing, oxide removal and deburring where suited to the process
Material selection depends on temperature and chemical contact at the brushing station, not simply the name of the process line.
FAQ
Can I replace individual discs instead of the complete roll?
Selected discs may be replaced where the shaft and retaining design allow disassembly. Match the remaining discs' condition, OD and fill specification, then confirm whether final trimming and runout or balance checks are required. Uneven wear may make a complete matched stack more suitable.
Can the shaft stay in the machine during replacement?
That depends on access and the assembly. A full-circle disc normally needs access from a shaft end; stacked discs do not automatically provide the same installation method as split-core brushes.
How does this differ from a spiral-wound brush roll?
A disc-type roll uses separate metal brush discs stacked along the shaft. A spiral-wound brush uses brush strip wound helically around a core. The construction affects fill layout, density, retention and replacement. Neither is universally better for every line.
Which abrasive and grit should I choose?
Start with the existing successful specification and the required surface finish. Abrasive, grit, filament diameter and contact load work together; wet-line chemistry and temperature also affect selection. A trial may be needed when changing the specification.
