Carbon Brushes

Aircraft carbon brushes are indexed in this category by exact drawing number, brush family and execution. These contact components may be recorded for different generators, motors or other electrical machines, so a general description is not enough for selection. The complete designation from the technical record or removed brush should lead the search.

Drawing numbers and MGS brush families

The catalogue contains 555-series positions associated with MGS-7 and MGS-8 families, including versions separated by suffixes, as well as other recorded brush designations. A shared family reference does not establish identical geometry, material grade, lead arrangement or electrical application. Each drawing number remains an independent product identifier.

Dimensions and execution require documentary confirmation

Brush selection can depend on cross-section, working length, terminal or flexible lead, contact arrangement and the electrical machine in which it is installed. Do not infer these parameters from a neighbouring number. Compare the designation with the machine parts list, drawing and applicable maintenance data before requesting supply.

• copy the complete drawing or Part Number;
• state the MGS family or electrical machine;
• include documented dimensions when available;
• describe the terminal or lead execution;
• add quantity, document requirements and photographs.
