Plastic balls, We are professional supplier of plastic solid balls with all diameters in material POM ( Delrin),PP, HDPE,PS,... POM Balls: Material: POM(Delrin) Size: 2.38mm~50.4mm(3/32"~2") Plastic Balls Introduce Plastic balls are deal 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 are produced using standard and special polymer resins with diameters from 2.0 to 50.8 mm. and they can be used instead of stainless steel or steel balls in various industrial applications at lower cost than metal balls.

The most common applications include plastic bearings and rollers, ball bearings for furniture, micro-pumps for sprays, dispensers, pumps and valves, precision instruments, measurement and control equipment, photographic and pharmaceutical equipment, com­puters, conditioning and automation equipment, photocopiers and equipment for the industry.

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 300°C.

 

Plastic balls offer above all the advantage of being very light, sinces their specific weight is very low. They are also highly resistant to heat and they provide smooth and silent running, totally noise and friction free. Unlike conventional metal balls they do not requi­re lubrication,Another important feature is their excellent resistance to oxidation and abrasion and, therefore the use of these balls, even in very corrosive environments, allows long life of the component concerned. They also provide electrical and heat insulation and are not magnetic.

 

There are a variety of plastics available and each has different characteristics, so feel free to contact us and we will help you select the polymer best suited for your application and budget.

 

 

below for physical properties:

 

POM Balls (DELRIN) is similar to nylon but slightly harder and denser. Recommended for applications where these properties and low water absorption are required. Balls made of these materials are often used for sliding fittings of tables and drawers, furniture bearings, rollers, valves and elec­tronic components, sailing boat fittings.
