This 2-pack carbon brush kit is made by Ametek Lamb, part number 833392-61, for vacuum motors built by Ametek Lamb. Ametek Lamb motors are used across many vacuum brands, so this kit may fit machines beyond a single manufacturer.

Carbon brushes wear against the motor's commutator to conduct current to the armature; replace both brushes in the kit together for even wear. Confirm the motor part number stamped on your machine before ordering, since Ametek Lamb produces multiple motor variants.
