This is a 950-POLOLU Ball Caster with 3/8" Plastic Ball.

This small, light ball caster uses a 3/8" diameter plastic ball. The height of the assembled kit ranges from 0.4" to 0.6".

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.
