Description

Overview

This ball castor kit includes a black ABS housing, a 3/4″ diameter metal ball, two spacers (1/16″ and 1/8″ thick), and two #2 screw sets. The total height of the ball castor, 0.83″, can be increased to about 1″ using the included spacers. The two included #2 screws can be used to mount the ball castor to your chassis (the distance between the screw holes is 0.61″).

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.
