Plastic Balls
Plastic balls are an effective, economical substitute in low load bearings, agitators in aerosol spray cans, and in lightweight check valves. Plastic is lower in cost and used where weight is not an issue, or a lightweight material is desired. Abbott can supply plastic balls in Acetal, Celcon®, nylon, Delrin® and Polypropylene. Plastic ball surface finishes may vary from coarse to highly polished, according to customer specification. Various colors and fillers are also available. Plastic balls are offered in a range of sizes and tolerances (grades).
