Cup Brush Seals
A cup brush is basically a strip brush looped
laterally to form a dish shape. These are made to suit a particular
task. They are most often used as a seal around a cylindical
rotating piece, like a drill bit or grinding device. The cup brush
shields the operation from chips or dust flying into its surrounding
area.
Cup brush
seals can be formed in full circle or in segments. Cup
seals can be formed with straight sides or at various
angles. Cup brush seals can be used as vacuum brushes or
as a seal around drills, cutter and routers. Larger size
cup brushes are used in swimming pool cleaners and
gutter brooms.
