- Easy to assemble
The Pololu Ball Caster with 1/2" Plastic Ball includes a black ABS housing, a 1/2" diameter plastic ball, two spacers (1/16" and 1/8" thick) and two #2 screw sets. The total height of this ball caster is 0.53" with no spacers. You can also adjust the height by adding the spacers. The ball caster can be mounted to a chassis by the two screw sets included in the kit. The distance between the two screw holes is 0.58".
*Note: These 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.
