Pololu Ball Caster with 1″ Plastic Ball and Ball Bearings
This ball caster uses a 1″ diameter plastic ball and has an overall height of 1.1″ (29 mm). The two-part housing snaps together to securely enclose the ball and three ball bearings that minimize friction between the ball and the ABS housing. The base piece of the housing has holes for three #4 or M3 screws (not included).
