Description

The GE 266A984AFP17 Carbon Brush is a heavy-duty electrographitic carbon brush with Morgan T573 grade material, original OEM spare part for General Electric large DC motors, cross-referenced as Repco REP1053W. It is built as a dual-wafer split brush assembly, engineered for high-torque, heavy cyclic load applications in steel, mining and power industries. Made of premium impregnated electrographitic carbon compound, it maintains consistent sliding contact and stable current transfer under frequent load fluctuations. 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.
