50mm Carbon Fiber Static Wheel Brush

A 50mm Carbon Fiber Static Wheel Brush is a cylindrical wheel brush engineered for dry, grounded-contact dust removal on static-sensitive equipment and materials. Carbon fiber filaments are filled around a 6061 aluminum hub and trimmed to a flat, rectangular contact face 50 mm in diameter and 20 mm wide.

In use, the wheel is mounted on a shaft, arbor, or grounded holder. The part, web, or roller either passes under the fixed wheel or contacts a rotating wheel. As the filament tips touch the surface, static charge flows through the carbon fiber into the aluminum hub and out through the machine ground. Once the electrostatic grip is removed, loose dust and fibers release for capture by a vacuum hood, adhesive roller, or downstream collection point.

This is a dry-cleaning contact component, not a scrubbing brush. It removes loose, static-attracted particles and may be used with an ionizing bar or vacuum for a complete particle-removal station. Ground continuity between the aluminum hub and the machine frame is essential to its function.

• Electronics assembly lines: PCB conveyors, stencil printers, depaneling stations, and pre-inspection positions where loose fibers, powder, and static-attracted dust must be removed before soldering, AOI, conformal coating, or final assembly.
• Web and sheet converting: film, paper, and foil lines where static charge holds dust to the web before printing, coating, lamination, or slitting.
• Roll and roller cleaning: contact cleaning of process rollers that transfer particles back to product, especially in dry, low-humidity environments.
• Display, glass, and optical sheet handling: gentle removal of loose particles from glass, acrylic, and optical film surfaces before lamination or coating.
• Cleanroom fixtures and tray cleaning: fixed grounded brush positions that wipe dust from jigs, carriers, trays, and static-sensitive work surfaces during transfer or return.

Start with the residue and the surface. This wheel is designed for loose, dry, static-attracted particles such as dust, fibers, and powder. If the contaminant is oil, grease, adhesive, solder paste, or baked-on material, the carbon-fiber contact will not remove it and the wheel will load up. Choose a wet, solvent, or abrasive cleaning method instead.

Check the contact width you need. The standard configuration covers a 20 mm band. For wider webs, panels, or roller faces, use a multi-wheel assembly on a common shaft or ask for an extended face width. The wheel must make light, consistent contact without pressing hard enough to bend the hub or stall the surface motion.

Verify the mounting and grounding interface. The aluminum hub must mount to a shaft or holder that is electrically bonded to machine ground. Provide the bore diameter, keyway or set-screw requirements, and the available ground connection. If the brush floats on an insulated bracket, it cannot dissipate static and becomes an ordinary dusting wheel.

Decide whether the wheel should free-roll or be driven. Free-rolling wheels work well on moving webs and parts. Driven wheels are used for stationary parts or when you need controlled filament flick and surface dwell time. For driven applications at higher rotational speeds, specify the maximum RPM so the assembly can be balanced and the filament retention checked.

Use a different brush when the job needs stronger mechanical action or wet exposure. A conductive metal-filament brush may be more appropriate for aggressive scrubbing, while conductive-nylon or natural-fiber configurations may suit washdown or food-contact areas. Carbon fiber is the choice when you need gentle, dry, grounded dust removal on static-sensitive surfaces.

Yes. The 50 mm diameter and 20 mm face width are the standard base, but most production parameters can be adjusted to the line layout and the grounding design. To define the configuration, we need the surface material and width, line speed or use mode, required contact force, shaft or holder dimensions, available ground point, and any controlled-space requirements.

We can adjust:

• Wheel geometry: outside diameter, face width, trim profile, number of fill rows, and segment width for multi-wheel arrays.
• Filament: carbon-fiber grade, filament diameter, density, trim length, and tip treatment to match dust type and surface sensitivity.
• Hub and mounting: bore diameter, keyway, set screws, clamping flanges, shaft adapters, or alternative conductive core materials when weight or chemical resistance matters.
• Grounding interface: direct shaft-contact bonding, grounding screw, or other reliable conductive connection to the machine frame.
• Configuration: single wheels, spaced multi-wheel assemblies on one shaft, or continuous wide-face builds.
• Project support: dimensional inspection, material declarations, conductivity measurements, and other verification steps can be arranged for the specific project requirements.
