This light ball caster is designed for small robots and uses a 1.875 cm diameter metal ball. The height of the assembled kit ranges from 2cm to 2.75cm. This ball caster kit includes a black ABS housing, of 1.875 cm diameter metal ball, two spacers (0.16 cm and 0.31 cm thick), and two #2 screw sets. The total height of the ball caster, 2.075 cm, can be increased to about 2.5 cm 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 1.525 cm).

This ball caster is not intended to bear more than a few hundreds of grams. With more weight than this, friction between the ball and the housing will probably keep it from rolling well.
