Pololu ball caster with 3/8" metal ball with included hardware. |
---|
This ball caster kit includes a black ABS housing, a 3/8" diameter metal ball, two spacers (1/16" and 1/8" thick), and two 7/16" #2 screws and nuts. 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, or you can use your own #2 or M2 screws if your application requires a different length.
Note that Pololu's 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 generally keep it from rolling well.
For detailed dimensions, see the dimension diagram (164k pdf).
