Plastic Balls

Plastic Balls

Plastic balls are manufactured from standard and specially polymer resins in size from 3/32″ – (2.381 mm) to 5″ -(127 mm). Balls above 1″ – (25.4 mm) are manufactured from extruded rod.

Plastic balls are a cost-effective substitute for metallic balls in low load bearings. They are also used as agitators in aerosol spray cans, lightweight check valves, medical diagnostics and a wide variety of other applications.

Tolerances to +/-0.0005″ (+-0.0125 mm) are possible for certain materials such as nylon and acetal. Surfaces can be tailored from rough to highly polished finishes.
