Pololu Ball Caster with 1/2" Metal Ball
This ball caster uses a 1/2ā³ diameter metal ball. The height of the assembled kit ranges from 0.5ā³ to 0.8ā³, depending on the combination of included spacers used.
This ball caster kit includes a black ABS housing, a 1/2ā³ diameter metal ball, two spacers (1/16ā³ and 1/8ā³ thick), and twoĀ 7/16ā³ #2 screwsĀ andĀ nuts. The total height of the ball caster, 0.53ā³, can be increased to about 0.7ā³ using the included spacers. The two included #2 screws can be used to mount the ball caster to your chassis, or you can use your own #2 or M2 screws if your application requires a different length.
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 generally keep it from rolling well.
