Ring brushes are composed of filaments arranged around an internal metal ring and pressed between two metal ferrules (see Figure). The result is a brush in the shape of a narrow disc with flange and circular bore.
The main characteristic of the rings is their modular design. They can be used individually, although they are more frequently mounted in a stack on a shaft to form a roller brush.
Density can be adjusted by inserting distance collars between each ring brush.
