Black Ball Caster with 3/8" Plastic Ball

Black Plastic Ball Caster - 3/8" - Pololu 950

This small, lightweight black plastic ball caster comes with a 3/8" diameter plastic ball. The height of the fully assembled kit ranges from 0.4" to 0.6", and can be customised by varying the combination of the included spacers used. With the included #2 screws the housing can be mounted to a chassis of your choice, or you can use your own #2 or M2 screws for a greater flexibility if you require a different length. The ball caster is designed for use in a small robot; they are not intended to be under more than a few pounds of load. If a greater load is applied, friction between the ball and the housing will generally keep it from rolling well.
