Description

National 36A164452AAP05 Carbon Brush T566 is a premium two-wafer split electro-graphite carbon brush manufactured as direct OEM replacement for General Electric heavy-duty DC motors and generators. This carbon brush features T566 electro-graphite material with 0.875” × 1.500” × 3.250” dimension and twin wafer split construction. The dual wafer design effectively suppresses cross-currents, reduces electrical sparking and maintains a stable protective film on the commutator surface under heavy and fluctuating industrial loads. The resin-impregnated carbon block delivers consistent conductivity, low friction and extended service life in harsh factory environments. It comes fitted with a 4.5-inch multi-strand tinned copper braided shunt firmly crimped to the carbon assembly, resisting vibration fatigue. The U-0.281” bent hammer plate terminal ensures secure installation inside matching GE brush holders. Commonly used in steel rolling mills, mining draglines, power generators and paper processing machinery. Precision machined dimensions guarantee perfect fit for scheduled overhaul and maintenance of large GE DC rotating equipment.
