Product Overview
A deep-reach constant-force carbon brush spring designed to fit recessed brush holders in generators and alternators. The extended reach ensures consistent contact pressure even in deep-cavity housings where standard springs cannot access the commutator effectively. Reduces brush sparking and EMI in deep-holder configurations. Maintains constant pressure for commutator regardless of brush length — ideal for generators and alternators with compact, deep brush housings.
