100x500mm PA66 Conveyor Roller Brush

A 100x500mm PA66 Conveyor Roller Brush is a cylindrical brush roll built for automatic conveyor cleaning. The size designation refers to a 100 mm outside diameter and a 500 mm usable brush face, not including shaft stub ends. PA66 nylon filaments are anchored into a powder-coated carbon steel core, and the assembly mounts through a quick-change coupling onto a driven or idler shaft.

In operation, the roller is positioned across a belt, return run, pulley, or transfer point so the filament tips contact the moving surface. The brush can rotate in the same direction as the belt for gentle sweeping, or against the belt for more aggressive flicking and debris removal. Most installations place the roller just after the belt discharge at the head pulley, under the return strand, or beside a product path where spillage and dust collect.

This product is intended for loose, dry, or lightly tacky debris that can be knocked off by mechanical brushing. It is not a scraper for hardened deposits, and it does not replace a wash station for heavy wet carryback. In many plants it works alongside a belt scraper or spray system as the first mechanical stage of the belt cleaning sequence.

The table below lists the standard configuration. Dimensions and materials marked as adjustable can be changed to match your conveyor geometry, drive, and cleaning requirements.

Shaft diameter, keyway, bearing journal size, and rotation direction are specified at order time so the roller drops directly into your existing conveyor assembly.

• Bulk material handling conveyors — removes carryback of aggregate, sand, grain, wood chips, and recycled material from the belt return side before it accumulates under the frame.
• Food and bakery lines — sweeps flour, sugar, crumbs, seeds, and small product fragments from belts, especially before product contact or before the return run.
• Packaging and carton operations — clears paper dust, label fragments, film scraps, and boxboard fibers that can interfere with seals or contaminate product.
• Textile and web converting lines — removes lint, fibers, and dust from rollers, guide surfaces, and transfer points.
• Return belt and pulley sections — mounted below the belt or against the head/drive pulley to knock off material before it builds up.
• Transfer points and machine guides — positioned to sweep loose debris from rails, guides, and support surfaces near material drops.

Start with the mounting envelope. Measure the clearance between the belt or product surface and the nearest obstruction. The 100 mm OD needs at least about 105–110 mm of space including runout and mounting brackets. Face length should match the belt width or the contact zone you need; if the belt is wider than 500 mm, use two or more roller brushes or request a longer face.

Next, match the filament to the debris. Fine dry dust and powder usually call for 0.30–0.50 mm filaments in a higher-density fill, giving many fine tips for gentle surface brushing. Chips, fibers, label pieces, and film fragments benefit from 0.50–0.80 mm or crimped filaments that provide a stiffer, more aggressive flick. Sticky carryback may require the stiffer side and a stripper bar to prevent the brush from loading up.

Select the core and interface for the environment. Powder-coated carbon steel is the standard choice for dry or mildly humid ambient conditions. For washdown areas, food processing, or corrosive exposure, specify a stainless steel core and compatible end fittings. Confirm the quick-change coupling type and shaft dimensions against your existing drive before ordering.

Set operating parameters deliberately. Engagement depth of 2–5 mm gives effective cleaning without excessive filament wear. Opposite rotation relative to belt travel produces better debris removal; same-direction rotation is a gentler sweeping action. If the process temperature exceeds 80°C continuously, PA66 may soften or lose stiffness, and a higher-temperature filament material should be considered.

The 100x500mm configuration is a common stock size, but almost every dimension and material can be adjusted. When you request a custom roller brush, the most helpful information to provide is belt width, belt speed, debris type, wet or dry conditions, process temperature, available clearance, and the drive or bearing interface dimensions.

Common customization options include:

• Dimensions — face length from shorter than 500 mm to 2000 mm or longer, outside diameter from 60 mm to 200 mm or more, core diameter and wall thickness.
• Filament — diameter from 0.10 mm to 1.00 mm, straight or crimped style, trim length, density, filament color, and hardness variations within the PA66 family.
• Core and shaft — powder-coated carbon steel, stainless steel 304/316, keyed bore, plain bore, stub shafts, bearing journals, or drive flats as required.
• Connection — quick-change coupling type, shaft end geometry, and mating dimensions matched to your existing drive components.
• Optional features — stripper bar or comb, end discs, balancing for high-speed service, mounting brackets, and filament color coding for identification.
• Packaging and marking — bulk packing, individually wrapped rolls to protect filament shape, labels, tags, or barcoding for warehouse handling.

If your project requires material documentation, inspection reports, or third-party testing for the filament or core materials, we can support those requirements during the customization process.
