Custom spiral roller brushes for conveyor cleaning, washing, wiping, guiding, and other continuous-process contact. Built for your machine layout and required brushing result.
Request a QuoteA spiral brush, also called a spiral roller brush, is made by winding strip-brush material around a shaft, core, or holder so its external working face follows a continuous helical path.
Open or close winding creates the contact coverage needed across a moving line, roller, or rotating assembly.
This page covers exterior spiral roller brushes for conveyor cleaning, washing, wiping, guiding, and controlled process contact. For internal bores and tube passages, use a pipe brush instead.
Choose the winding density and band construction first. Core, shaft, and mounting details are then specified from the drawing for the installed roller.
Open-wound brushes leave space between turns for debris or liquid to pass. Close-wound brushes place adjacent turns together for denser, more continuous contact. Choose the pitch for the cleaning task, fill stiffness, and machine conditions; closer winding is not always the better option.
Individual spiral brush sections are internally welded to supporting rings and assembled on a common shaft. We manufacture replacement sections and complete roller assemblies to drawing for bulk OEM and repeat orders.
Worn sections can be replaced while retaining a serviceable shaft, depending on the mounting design and maintenance access. Check shaft straightness, journals, and drive connections before reuse, and match replacement-section diameters to adjacent sections for consistent contact. This can simplify replacement and help control maintenance costs.
Spiral-wound brushes are used where a helical brush face provides continuous or directional contact. Winding density, fill, backing, core, and direction are matched to the process line.
Open-wound spiral brushes remove carryback, dust, and loose material from belts, chains, and transfer lines. Winding hand, brush rotation, and product travel direction are specified together when the brush must also guide material or move debris laterally.
Close-wound nylon spiral brushes provide dense, continuous washing contact in horizontal glass washers and other flat-panel cleaning equipment. Filament diameter, face density, shaft construction, chemical exposure, and maximum RPM are reviewed for the machine.
Abrasive-nylon, non-abrasive synthetic, or confirmed wire fills can remove oil, rolling residue, oxide, scale, and other contamination or provide controlled surface activation and finishing. Typical positions include cleaning and degreasing, pickling and annealing, galvanizing, and coating lines for compatible steel, stainless steel, aluminum, and copper sheet or strip.
Steel-wire, abrasive-filament, or natural-fill spiral rollers can texture grain, remove loose fibres, denib, or prepare wood surfaces for finishing in brush sanders, drum sanders, and other woodworking equipment.
The filament or wire creates the working action, the backing channel secures the fill, and the core or shaft fits the machine. Each material group is selected separately for the process, environment, and approved drawing.
Nylon filament is used for washing, wiping, conveying, and controlled contact. Filament diameter and stiffness are matched to the surface and machine duty.
PP filament is available for wet cleaning and selected chemical-exposure applications where low moisture absorption is useful. Compatibility must be checked against the actual process liquid and temperature.
Silicon carbide or aluminum oxide abrasive grain is embedded in nylon filament for cleaning, deburring, oxide removal, surface activation, polishing, and controlled finishing. Abrasive type, grit, and filament diameter are selected together for the required result.
Tampico, horsehair, boar bristle, and ostrich feather for polishing, waxing, dust removal, and soft contact.
We can manufacture spiral brushes with carbon steel wire, galvanized steel wire, stainless steel wire, or copper-coated steel wire for stronger cleaning, oxide or scale removal, deburring, texturing, and surface conditioning. The wire grade is matched to the workpiece and contamination limits.
Stainless steel, galvanized steel, or cold-rolled steel backing is available for single- or double-band strip construction. Backing material and band construction are selected according to corrosion, washdown, chemical exposure, required fill density, and how the spiral is secured.
Steel, stainless steel, or another approved core and shaft material is selected according to load, corrosion, washdown, mounting, and operating conditions. Tube, journals, keyways, flanges, and other interfaces follow the approved drawing.
Reference layouts for OEM and replacement brushes. Dimensions and mounting details follow the approved drawing.
Pitch and clear gap. Pitch is the axial center-to-center spacing between adjacent turns. Clear gap is the edge-to-edge space; identify whether the drawing measures the backing or the brush face.
Winding hand and rotation. Right- or left-hand winding (RH/LH) is separate from operating rotation (CW/CCW). Mark the viewing end and any required lateral movement on the drawing; winding hand alone does not determine material travel.
We have manufactured spiral brushes in a wide range of sizes, winding patterns, and fill materials, from loose coils and replacement sections to complete roller assemblies.
