Pololu Ball Caster with 3/8" Plastic Ball

This ball caster kit includes a black ABS housing, a 3/8" diameter plastic ball,
two spacers (1/16" and 1/8" thick), and two #2 screw sets.
The total height of the ball caster, 0.4", can be increased to about 0.6" 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 0.53").

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.
