Carbon Brush with Spring – 26HY30004

Combining the graphite conductor with the spring that tensions it, this carbon brush arrives as a single serviceable unit for an electric motor's commutator. The spring is what holds the brush against the copper as the block wears down, maintaining steady contact pressure so current keeps flowing without the gaps and arcing that come from a brush riding loose in its holder.

Carbon brushes are consumables that wear a little with every hour the motor turns, and a motor that begins to spark, stutter, or fall off under load is often telling you its brushes have worn short. Fitting a fresh brush and spring together restores full spring travel and a full-length block at once, rather than pairing a new brush with a tired spring. Match the brush size and the spring style to the unit coming out, since both are cut to the specific holder they seat in.
