This light ball caster uses a 1″ diameter plastic ball. The height of the assembled kit ranges from 1.1″ to 1.4″. Dowel pins are used to minimize the friction between the ball and the ABS housing.

Note: We have released an improved ball caster with 1″ plastic ball that we recommend over this older version for applications that are not somehow specifically tied to this item #956 design. The new version has better rollers and it holds the ball more securely.

Overview

This ball caster kit includes a black ABS housing, a 1″ diameter plastic ball, three dowel pin rollers, two spacers (1/16″ and 1/8″ thick), and three #2 screw sets. The total height of the ball caster, 1.1″, can be increased to about 1.3″ using the included spacers. The three included #2 screws can be used to mount the ball caster to your chassis (the distance between the screw holes is 0.69″).

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.
