Description

National Carbon 36A164452AAP21 Carbon Brush T563 – 2 Wafer Industrial Motor Brush is a premium two-wafer split electro-graphite carbon brush built for General Electric large industrial DC motors and generators. It features T563 carbon grade with 0.875” × 1.500” × 3.250” dimension and twin wafer split design, which effectively suppresses cross-currents, reduces sparking and delivers stable commutator film under heavy fluctuating loads. This carbon brush comes with a heavy-duty 5.75-inch tinned copper braided shunt and bent U-style hammer plate terminal for secure installation inside original GE brush holders. The resin-impregnated electro-graphite material provides consistent conductivity, low friction and extended service life in harsh industrial environments. It is widely deployed in steel rolling mills, mining draglines, shovels and heavy industrial rotating machinery. Precision machined to OEM dimensional specifications, it is a direct drop-in replacement part for scheduled maintenance and overhaul of large GE DC motors and generators.
