Plastic Balls

Plastic balls are ideal for light load bearings and flow control applications. Plastic balls are often used in the construction of office furniture and medical equipment because of their quiet operation. Plastic balls are often used extensively in pharmaceutical, food and chemical production.
Plastic Balls have low friction and require virtually no lubrication. They are much lighter than metal balls and are resistant to corrosion and abrasion. Many plastics are also resistant to high temperatures up to 600° F.

POM Balls (Delrin®) Acetal is the common name for a family of thermoplastics with the chemical name “PolyOxy-Methylene”. Acetal provides high strength and stiffness, enhanced dimensional stability, and is easy to machine. As a semi-crystalline material, acetal is characterized by a low coefficient of friction and good wear properties.High strength, stiffness, dimensional stability // Very low moisture absorption // Good wear and abrasion resistance // Wide range chemical resistance (including many solvents)


Polyethylene Balls (High or Low Density)It is lightweight and soft.The high Density PE is more stress crack resistant than Polyethylene Low Density.

Polypropylene Balls are characterized by low weight and water absorption and resistance to corrosion. Typical applications include fluid level gauges, flow meters, valves, blood transfusion kits, vapor and evaporation shields for electrolytic solutions.
