This light ball caster uses a 3/4" diameter plastic ball. The height of the assembled kit ranges from 0.9" to 1.2". Dowel pins are used to minimize the friction between the ball and the ABS housing.

- 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.
