Carbon Brush for Bernina – Style (Compatible)

Replacement carbon brush for Bernina sewing machines — see the fit notes below for how to confirm it matches yours. This is a compatible replacement part rather than a manufacturer-original part.

What this part does

Carbon brushes carry current to the motor armature and wear down with use. They are the normal service item on a universal motor and are usually sold in pairs, with or without the springs and caps.

Specifications

How to tell if this is the right one

Match by the brush dimensions (width x depth) and the model list where given. Brushes are matched to the motor, not the machine, so a stated size is the surest guide.

Signs you need this part

The motor sparks heavily, runs erratically, slows under load or stops, often after a period of being sluggish. Brushes worn to under about 5 mm should be replaced.

Fitting it

Unplug the machine. Unscrew the brush caps on either side of the motor, withdraw the old brushes, fit the new ones with the curved face matching the commutator, and refit the caps. Run the motor at low speed for a few minutes to bed in.

Questions about this part

Which machines does this carbon brush fit?

The distributor's listing does not name specific models for this part, so we do not claim a fitment. Compare the specification on this page with the part you are replacing, or send us your machine's model number and we will check.

Do I replace one or both?

Both. They wear together and a new brush against a worn one causes uneven running.
