Holder Assembly & Carbon Brush Holders

Our Brush Holder Advantages

Enhanced design allows for longer brushes increasing brush life and decreasing downtime
Improved brass holder for durability in harsh environments
Holder material options: casted brass, extruded brass, Teflon^TM coated

Our pioneering research in the 1980’s set the industry standard for spring pressure, from 2 psi to 4-6psi.
Proper spring pressure ensures better brush contact with the commutator
Increased spring force reduces electrical brush wear thus improves brush life and performance
Spring life expectancy is 3-5 years on most applications – replacing our springs is easy and safer than traditional springs!

Optional brush wear indicator is the industry’s most convenient way to monitor brush wear
Red “danger strip” informs you the brush is worn out and should be replaced.
Preventative maintenance’s dream accessory

Impressively fast and easy way to change brushes
No screws to remove, lose or replace!
HQD’s lock together with a tight, positive locking action even under rough conditions
Increase maintenance safety
