Nominal ball diameter, DwDiameter value which is used for the purpose of general identification of a ball size.
Mean diameter of a ball DwmArithmetic mean of the largest and smallest diameter of a single ball.
Lot mean diameter DwmLArithmetic mean of the largest and smallest ball diameter Dwm in a batch.
Ball grade GA specific combination of dimensional tolerances, shape tolerances, surface roughness and sorting tolerances. Each grade is identified by number that is preceded by the letter G.
Class interval IGAmount in which the permissible deviation of the nominal ball diameter is uniformly subdivided.
Lot/BatchA definite quantity of balls that have been manufactured under identical conditions and which all exhibit practically the same properties.
Surface roughness RaCharacteristic value giving the surface roughness.
Class SDifference between the mean ball diameter of a batch (for VDwL) or part of a batch (for VDwA) and the nominal ball diameter Dw, rounded to an exact multiple of the class interval IG.
Class tolerance STPermissible range for DwmL within a class. The value of the class tolerance ST is identical to the class interval IG.
Deviation from spherical form tDwsThe greatest radial distance in every equatorial plane between a sphere circumscribed around the ball surface and any point on the ball surface.
Variation of the ball diameter within a batch VDwL Difference between the largest and smallest mean ball diameter Dwm within a batch. Only applies to grades G3 to G200 (except G80).
Variation of the ball diameter within a class VDwADifference between the largest and smallest mean ball diameter within a class. Applies to grades G80, G500 -G700 and for all types of special materials.
Ball diameter variation VDwsDifference between the largest and smallest diameter of a single ball.

Plastic balls are produced using standard and special polymer resins with diameters from 1.50 to 150 mm. and they can be used instead of stainless steel or steel balls in various industrial applications at lower cost than metal balls.Plastic balls offer above all the advantage of being very light, since 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. The most suitable type of synthetic material can be chosen from a wide range of plastics each with different characteristics.
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.
NYLON (PA)Insoluble in common solvents, alcalis, diluted mineral acids and organic acid substances. It is, above all, resistant to alcalis, oils and petroleum greases at temperatures up to 150 °C, inorganic saline solutions, aromatic hydrocarbons, low strength alcohols, gasoline. It has high strength, rigidity and hardness characteristics.DELRIN (ACETAL RESIN - POM)Polymer resin with excellent mechanical and chemical resistance and good electrical properties. Resistant to inorganic saline solutions, aliphatic, aromatic and chlorinated hydrocarbons, low strength alcohols, ether, combustible mixtures, mineral oils and greases. 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.POLYPROPYLENE (PP)Excellent chemical resistance, low specific weight (less than water) and the highest melting point of thermoplastics. It is an excellent electrical insulator and has a low dielectric constant coefficient. It is often used where the capacity to float on fluids in general is required. It is ideal for equipment used for blood transfusions, level indicators and deodorant roll-on sticks. It is highly resistant to chemical substances, such as acids, alcalis, alcohols and many inorganic substances, saline solutions, solvents, alcohols, gasoline (petrol), water, oils, greases, detergent, fruit juices and milk. It is not resistant to aromatic hydrocarbons and chlorates. It is perfect for all medical and pharmaceutical applications.
On request, we can supply further materials of plastic balls and glass fibres filled balls.
CERAMIC BALLS
Si3N4 SILICON NITRIDE
The most widely used type of ceramic due to very high resistance to wear and abrasion in general. It has a low coefficient of thermal expansion (25% of that of steel balls) and a weight 60% lower than steel. It has a micro-structure specially designed for applications subject to great stress. It does not require lubrication, it is resistant to corrosion, anti-magnetic and electrically insulating, and it continues to be efficient at high temperatures up to +1400 °C. It combines extreme hardness with a high precision ball. Si3N4 balls are widely used in high precision bearings in the airspace industry, for machine tools, measurement instruments, valves for automotive technique, compressors and fast turning hard disc.
AL2O3 ALUMINIA OXIDE
Alumina Oxide balls are particularly well suited for use in extremely harsh environments where high temperatures, corrosive and erosive substances are present. Standard 99.5% alumina oxide ceramic balls have proven performance in wear, heat and corrosive environments, as well as, in maintaining dimensional stability at temperatures up to 2000°F. Alumina resists oxidation and is tolerant to water, salt solutions, and many chemicals and acids, but is not suitable for use in hydrochloric or hydrofluoric acids or strong alkaline solutions. Typical applications include pumps, valves and flow meters
Zr02 ZIRCONIUM OXIDE
This material, compared has a high degree of compactness and considerable flexural strength, which makes it very reliable. It also has a low modulus of elasticity, close to that of steel, together with an extraordinarily low thermal conductivity.

Ceramic balls are widely used in strong conditons. Ceramic have a lower density than steel, a low coefficient of termal expansion and a very high hardness. They have a long life in very high velocitiy applications. The most important materials are Silicion Nitrid, Alumina Oxide and Zirconium Oxide.
