This is a new Helwig carbon brush holder, part number 22.371517.1.101, from the Helwig brush-holder series used on elevator/escalator machine motors (Otis-type) and similar DC commutator machines. The number follows Helwig's stock-part format (family prefix + base number + configuration suffix), and the 371517 base number corresponds to Helwig's elevator-machine brush family (companion brushes: 22-371517-400-3-01, 11-371517-870-2-09, HELW75-371517-811-4-26, sizes ≈0.370–0.375" × 1.5" × 1.70–1.75"). The holder provides the brush box, lead slot and mounting interface for the brush; the spring assembly is normally a separate Helwig stock item. As the exact brush-box size, stud spacing and spring configuration are not published for this specific suffix variant, confirm them against the original holder on the machine before ordering.
