Pololu Ball Caster with 1" Plastic Ball and Ball Bearings
This ball caster is an improved version of our original Pololu Ball Caster with 1″ Plastic Ball; we recommend this new version over the older version for all applications that are not somehow specifically tied to the previous design.
This ball caster kit includes a two-part black ABS housing, a 1″ diameter POM (also know as acetal or by the brand name Delrin) plastic ball, three 3×7×3mm ball bearings, and three dowel pins used to hold the ball bearings. When assembled, the ball caster is capable of rolling in any direction with low friction, making it suitable for use as a third contact point for wheeled, differential-drive robots weighing up to around ten pounds.
