What is the diameter of the shaft?

I have successfully used the brass inserts from large chocolate-block connectors for connections on some motor shafts.

Hi,
Do you mean THESE MOTORS?

I would really like to find attachments for these!

  • Servo horn
  • And especially Wheels to make small robots...

Anyone seen these?? Thanks!

The shaft on my version of the 28BJY motor is 5 mm in diameter, which is standard.

You need two setscrews, one on each side of a 5 mm bore gear to engage the flats.

Below is a picture of a pinion gear with a single set screw.
Imagine a second set screw on the opposite side of the shaft.

Instead of a servo horn or arm, consider using a hub, like this one (you would need a 5 mm bore).
