Pololu Ball Caster

by Pololu

This ball caster kit includes a black ABS housing, a metal ball (chose the correct size above), two spacers (1/16" and 1/8" thick), and two #2 screw sets.

The total height of the ball caster, 0.83", 0.53", or 0.4", can be increased to about 1", 0.7", or 0.6" respectively using the included spacers. The two included #2 screws can be used to mount the ball caster to your chassis

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.
