Description

The GE 266A983AFP16 Carbon Brush is a heavy-duty electrographitic carbon brush with Morgan T563 grade material, original OEM spare part for General Electric large DC motors, cross-referenced as Repco REP1052W. Constructed as a dual-wafer brush assembly, it is specially engineered for high torque, continuous cycling heavy-duty industrial applications. Made of premium impregnated electrographitic compound, it maintains consistent sliding contact and stable current transfer under fluctuating heavy loads. It forms a uniform protective patina on commutator surfaces, reducing sparking, friction and commutator abrasion. The bonded flexible stranded copper shunt ensures robust mechanical attachment and steady high-current conduction. Commonly used in steel rolling mill main drives, mining hoist motors and large industrial generator systems. Precision machined to original GE OEM specifications for direct drop-in replacement. Every 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.
