500mm PA66 Sweeper Module Brush

A 500mm PA66 Sweeper Module Brush is one of the replaceable bristle segments that make up the main broom of a mechanical road or yard sweeper. The operator does not hold this brush; it mounts into the rotating brush core above the sweeping deck, and the bristle tips contact the pavement as the core spins.

The module itself is a 500 mm long, 80 mm wide rectangular strip. PA66 nylon bristles project from the lower face in one or more rows, while the upper face carries the molded polypropylene snap-fit profile that locks the segment into the machine channel or cassette. When the brush roll rotates, each row flicks loose material from the surface into the machine collection path. Multiple modules are fitted side by side to cover the full broom width.

This configuration is a consumable wear component, not a complete brush assembly. It suits core-style sweepers designed for segmented replacement. Before fitting, the snap profile, segment pitch, bristle trim, and deck clearance all need to match the machine. On most routes, the correct installation will have the bristle tips deflecting slightly against the road surface under the machine brush-down pressure, not being flattened against the base.

The standard configuration is listed below. All dimension-dependent parameters can be adjusted to the machine.

• Municipal street sweeping fleets on asphalt and concrete roads where sand, winter grit, leaves, and litter accumulate in travel lanes and gutters.
• Construction and site-access roads where loose gravel, dried mud, and wood chips need daily clearing to keep vehicles moving.
• Industrial estates, distribution yards, and intermodal terminals with open-air hardstand areas exposed to dust and packaging debris.
• Airport apron and parking apron sweeping where dust, rubber particles, and small foreign-object debris require regular mechanical collection on runway-adjacent hardstand.

The brush performs best on dry or damp loose debris. It is not a wet scrubbing brush and is not intended to remove bonded stains, cured material, or heavy wet slurry by itself.

Four checks will get the best performance from the module.

Check the mounting system before anything else

Even though this is a 500 mm module, the snap-fit geometry is the make-or-break dimension. Measure the receiving channel width and retention slot position on the core, or send an existing module sample and a drawing. Confirm the segment depth and locking shoulder locations match before ordering a quantity.

Match filament diameter to the debris you sweep

Use 0.80–1.00 mm filament for fine dust and smooth asphalt where light flicking action cleans well. Move to 1.20–1.60 mm filament for gravel, construction spoils, leaf mats, or regular gutter debris, where thicker bristles resist bending and maintain the flick angle. Mixed diameters are possible in project-specific rows.

Set trim length from the deck, not the supplier catalog

Bristle trim is determined by the distance from the underside of the base to the road at the machine normal brush-down setting. The tips should make positive contact without being forced flat. If the trim is too short, the roller may not reach the surface; if it is too long, the bristles fold sideways and the module wears unevenly and pushes debris.

Think about replacement pattern

PA66 wears predictably, but it still shortens. Fleet operators should record brush-down pressure and track module wear per route. Higher row density and thicker filament extend the interval on abrasive routes while producing a firmer brush feel on the road. When it is time to replace, change the full set across a roller section to keep the contact line even.

When to use a different brush

• The machine core uses bolted, clamped, or welded segments rather than snap-fit channels. A snap-fit module will not secure reliably; specify an alternate base.
• The main debris is hardened or bonded material such as packed clay, scale, or stone baked into asphalt. A steel wire or mixed wire and poly module is more appropriate for cutting through it.
• The application is a walk-behind floor sweeper or a manual broom. This module is a machine-mounted service part for rotating cores.

Yes. The 500 mm length is the standard segment, but the product is normally configured to the machine. A customer-specific module can be built once we know the machine model or see the old segment.

• Snap-fit geometry: tab width, shoulder depth, retainer lip shape, end notches, and clip spacing matched to the core channel.
• Module dimensions: 500 mm standard, other segment lengths and base widths for non-standard roller pitch, plus base thickness changes for channel depth.
• Bristle system: PA66 filament diameter, trim length, row count, tuft spacing, fill density, and color. Optional UV-stabilized or low-temperature-impact nylon grades for special routes.
• Base material: PP as standard; reinforced or slightly modified PP where extra impact or cold-weather toughness is needed.
• Marking and packaging: part number printing, batch and lot marking, bulk cartons, shrink-wrapped sets, or individually labeled modules.

To define the configuration, send the roller core or brush cassette drawing, a sample worn module if available, deck clearance or bristle trim, typical debris type, and the number of modules per roller. If the project needs material declarations, inspection reports, or third-party testing for a bid package, we can support those requirements during project confirmation.
