RING BRUSHES - GENERAL

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.


 RING DIMENSIONS

The outside diameter of the rings is theoretically unlimited. However it must be considered that since the ring has a relative small metal core, very long filaments will tend to flex unacceptably. In practice we can consider a maximum diameter of around 500 mm with very coarse filaments.
The minimum diameter depends on ferrule dimension Db, which can be found in the table 3.1 in reference to the Figure 3.2. The thickness values S are guideline.
