Pololu Ball Caster with 0.5 inch Plastic Ball

This ball caster uses a 0.5″ diameter plastic ball. The height of the assembled kit ranges from 0.5″ to 0.8″, depending on the combination of included spacers used.

This ball caster kit includes a black ABS housing, a 1/2″ diameter plastic ball, two spacers (1/16″ and 1/8″ thick), and two 7/16″ #2 screws and nuts. The total height of the ball caster, 0.53″, can be increased to about 0.7″ 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 this ball caster is 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.
