Pololu Ball Caster with 3/4″ Plastic Ball
This light ball caster uses a 3/4″ diameter plastic ball. The height of the assembled kit ranges from 0.9″ to 1.2″, depending on the combination of included spacers used. Included dowel pins can be used to reduce the friction between the ball and the ABS housing, but they are not necessary for operation.

- How much weight can Pololu ball caster support?
- Our ball casters are designed for small robots; they are not intended to bear more than a few pounds. With more weight than this, friction between the ball and the housing will probably keep it from rolling well.
