Outside Diameter: 3/4Number of Items: 10 Verified Purchase
I am not exactly sure what these ball were meant for, but my 1920s treadle powered National - Eldredge Chain sewing machine uses one as a jam lock to prevent reverse operation of the treadle's drive wheel.

While 10 is an extravagant number for for a single treadle machine, it is handy to have extras since the roll away easily when dropped and are easily lost.

They seem well made and smoothly finished.

I bought these for a demonstration and laboratory for my high school physics class. They roll, they accelerate, the work. Not really sure why anyone would buy rubber balls, but I bought them along with several different diameter steel balls to recreate Galileo's experiments with acceleration on an inclined plane.
