Where it is used
Components of this type are fitted to the electrical and control system on industrial engines and lift trucks. This is category-level context, not a fitment list — confirm the part number against your machine's model and serial number before ordering.
Service notes
Replace brushes as a complete set and inspect the commutator. Running past the wear limit scores the commutator, which turns a cheap service into a motor rebuild.
