This ball caster kit includes a black ABS housing, a 12.7mm diameter metal ball, two spacers 1.59mm and 3.18mm thick, and two screw sets. The total height of the ball caster, 13.46mm, can be increased to about 17.78mm using the included spacers. The two included screws can be used to mount the ball caster to your chassis (the distance between the screw holes is 14.73mm).
Note that ball casters are designed for small robots; they are not intended to bear a significant amount of weight and, as such, would not be suitable for building things such as tables. With too much weight friction between the ball and the housing will probably keep it from rolling well.
- Ideal for Robot designs.
- Comes with 2 x spacers and mounting screws.
- 1 x 1/2inch (12.7mm) Diameter Metal Ball Caster and Accessories.
