Description

This General Electric 323B7987P01 carbon brush (also listed as GE 61044555) is a direct OEM-style replacement for GE commutator machines. The brush body is pressed from natural graphite (grade 634) — a material chosen for stable current transfer, low contact drop, good filming on copper commutators, and even wear over long service life.

Features & benefits:

OEM-matched dimensions — 1.0" × 1.5" × 4.0" (25.4 × 38.1 × 102 mm) wafer, drop-in fit for holders sized for GE 323B7987P01.
Grade-634 natural graphite — balanced conductivity, hardness and friction for reliable commutation with minimal arcing and commutator wear.
5-1/2" flexible copper shunt — tinned braided lead with spade terminal, resists fatigue and keeps a stable connection to the brush box.
Cross-referenced part numbers — GE 323B7987P01, GE 61044555, Repco REP2640A, Morgan AM&T 61044555, grade 634.
Typical applications — GE DC motors, DC generator field and commutator service, generator and wind-power motor applications.
