Profax Brush Seater & Commutator Cleaning Stone – Precision Seating for Carbon Brushes

Precision seating and surface refresh for carbon brushes

When a machine jumps an arc after installing new brushes, subtle surface conditions on the commutator or slip rings can be part of the cause. The Profax Brush Seater & Commutator Cleaning Stone provides a controlled, mild abrasive action to help seat carbon brushes and refresh the surface of commutators without aggressive material removal. Sized at 5/8" x 1-1/8" x 4-3/4", the stone fits easily into typical service workflows and sits comfortably in the hand for precise control.
