952-POLOLU Ball Caster with 1/2″ Plastic Ball

This light ball caster uses a 1/2″ diameter plastic ball. The height of the assembled kit ranges from 0.5″ to 0.8″.

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 #2 screw sets. 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 (the distance between the screw holes is 0.58″).

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.
