Description

The GE 4958442 Carbon Brush is a heavy-duty electrographitic carbon brush, OEM spare part for General Electric DC motors and slip ring assemblies, cross-referenced as Repco REP567. It adopts Grade H electrographitic material with single wafer 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 and slip ring surfaces, reducing sparking, friction and surface abrasion. The bonded flexible stranded copper shunt provides strong mechanical bonding and reliable high-current conduction. Commonly applied in steel rolling mill drives, mining hoist machinery and large industrial generator 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.
