Roller (cylindrical) brushes

A cylindrical brush is the working element of most cleaners: filament wound or implanted over a core on a shaft. The key dimensions are working length, total length, outside diameter, core diameter and the filament itself.

Design variants

Wound filament

Filament wound between flanges or in a spiral; replacement means rewinding or replacing the roller.

Implanted (tufted) filament

Filament tufts anchored into the core; individual tufts cannot be replaced in service.

Segment-mounted filament

Filament carried on removable segments fixed to the shaft; segments are replaced individually.

Dimensions to check

Parameters for a roller brush request

ParameterWhat to state
Working lengthThe brush length that cleans the belt along its width.
Total lengthShaft length including journals and bearing seats.
DiametersOutside diameter over the filament and core diameter; new and worn values if available.
FilamentMaterial, diameter and free length as stated by the manufacturer.

Limits and caveats

  • Numerical properties of specific rollers are published only with a source; this page lists generic dimensions.
  • Worn diameter reduces peripheral speed at the same rotation rate — see the brush speed tool.
  • Dynamic balancing and maximum speed are manufacturer responsibilities.
Front view and cross-section: The front projection shows the working and total length; the cross-section shows the core, filament layer and outside diameter. Together they describe the roller for a request.

Measure the worn roller directly: diameter over filament, working length, seating.
