Description

The GENERAL ELECTRIC 36A164456AAP21 Carbon Brush is a heavy-duty electrographitic carbon brush, OEM spare part for General Electric large DC motors and generators, cross-referenced as Repco REP1050W. It adopts Morgan T563 electrographitic material with dual-wafer split construction, engineered for continuous heavy-cycle industrial operation. Made of premium impregnated electrographitic carbon compound, it maintains stable sliding contact and consistent current transfer under variable heavy loads. It forms a uniform protective patina on commutator surfaces, reducing sparking, friction and commutator abrasion. The bonded flexible tinned stranded copper shunt with bent U terminal provides strong mechanical bonding and reliable high-current conduction. Commonly applied in steel rolling mill drives, mining hoist machinery and pulp & paper mill production systems. Precision machined to original GE OEM specifications for direct drop-in replacement. Each batch undergoes strict quality inspection for resistivity, hardness and wear performance. Bulk supply and worldwide shipping available for industrial maintenance contractors and heavy industry operators.
