Micromotor Spare Parts

Carbon brushes, armatures, chucks, cords, bearings and foot pedals for Marathon and Strong micromotors.

Why it matters

What This Category Fixes at the Bench

Most micromotor failures are one small worn part. A set of carbon brushes or a chuck costs a fraction of a new motor, but only if the lab can actually source the part for the model it owns.

Problems it removes

  • Carbon brushes wear out on a predictable schedule and are rarely stocked before they fail.
  • A worn chuck lets the bur run out of true, which shows up as chatter marks on the work.
  • Cords and foot pedals fail from flexing long before the motor itself is worn out.

Who buys it

  • Laboratories maintaining their own equipment
  • Equipment service technicians
  • Dealers offering after-sales support on micromotors

Answers

Micromotor Spare Parts: Buyer Questions

How often should carbon brushes be replaced?

It depends on hours of use and load, not on a calendar. The practical signal is torque: when the motor slows noticeably under a cut it used to make easily, inspect the brushes. Labs running a full day usually keep a spare set on the shelf.

Are the brushes for Marathon and Strong the same?

No. They are catalogued separately because the holders and dimensions differ. Order by the motor brand and model you own.

Can I order spare parts together with a new machine?

Yes, and it is the cheaper way to do it. Adding brushes and a spare chuck to an equipment order costs almost nothing in freight compared with shipping them on their own later.
