Industrial 65705K31 Carbon Brush DC Motor Assembly

Industrial 65705K31 Carbon Brush DC Motor Assembly is a two-pack of Ace Carbon ST-417 carbon brushes designed as replacement contact elements for motors that use the ST-417 brush geometry. Each brush measures 3/8 in. wide x 11/16 in. high x 1/4 in. thick, and the package includes two brushes per order. This part is listed as 65705K31 and is available as NOS surplus from Ace Carbon, making it a direct swap-in for compatible DC motor applications that require the ST-417 style. Carbon brushes provide the conductive path between stationary components and the rotating commutator, and they wear during operation, so replacing worn brushes helps maintain electrical contact and motor performance. Compatible use typically includes small to mid-sized brushed DC motors that require the 3/8 in. wide by 11/16 in. high by 1/4 in. thick brush geometry, with the 65705K31 designation distinguishing this exact size from other 65705Kxx variants.
