Pololu Ball Caster with 3/4 Inch Metal Ball
This ball caster kit includes a black ABS housing, a 3/4 Inch diameter metal ball, two spacers (1/16 Inch and 1/8 Inch thick), and two #2 screw sets. The total height of the ball caster, 0.83 Inch, can be increased to about 1 Inch using the included spacers. The two included #2 screws can be used to mount the ball caster to your chassis (the distance between the screw holes is 0.61 Inch).
Note that 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.
