S-2 Tool steel balls are design to achieve extreme ruggedness. The ball surface has smooth ground and polished finish. These balls provide the toughness and strength necessary for severe shock loads. S-2 Tool steel balls are hardened throughout and have unusually good wear characteristics. S-2 Tool Steel Balls find most frequent use in oil field equipment and offshore drilling operations. They provide good service in withstanding the abrasion of pulverized rock and mud slurries.  

The most widely used type of ceramic due to very high resistance to wear and abrasion in general. 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, mechanical centrifuges, radar and missiles, pumps and compressors.

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.

Burnishing Media can be balls or peculiar shapes which are used for polishing the rough surfaces of many different metal components. The different shapes are designed to get into the varying crevices and contours of diverse metal products.  

Glass Balls are dimensionally stable, resist corrosion and chemical absorption and can withstand high temperatures (up to 600 °F .) Density varies depending on the type of glass used to manufacture the ball. We provide high precision balls from the following types of glass: SODA-LIME GLASS : Material resistant to high alkaline solutions. Soda-lime glass balls are mainly used for applications not subjected to strong mechanical or thermal shocks, such as plastic bearings, flow meters, measurement and control equipment, instruments and ink cartridges. BOROSILICATE GLASS : Due to its excellent chemical inertia to most acids, this kind of glass is particularly suitable for metering pumps and valves against strong oxidising concentrations. BLACK GLASS : A kind of glass often used for medical and chemical flow meters and for general measurement and control instruments.

ceramic balls are particularly suited to harsh environments. Their main advantages over steel is that they have a density of 40% tower than steel. Have 29% lower thermal expansion and are 150% harder. In certain high-speed applications their life is extended by as much as a hundred times. The three main materials used are alumina oxide, zircona oxide and silicon nitride. si3n4 silicon nitride: the most widely used type of ceramic due to very high resistance to wear and abrasion in general. 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, mechanical centrifuges, radar and missiles, pumps and compressors. al2o3 99.50% alumina (alumina oxide): the material has a multi-crystal structure and excellent resistance to abrasion and high temperatures. It is resistant to most corrosive agents, but it is not recommended for use in contact with hydrochloric and hydrofluoric acid or strong alcaline solutions. Al2o3 balls are used in valves, pumps and ball bearings. zro2zirconium oxide: the 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. al2o3 99.99% ruby: this material has a non porous single crystal structure used where particular hardness and extreme resistance to wear are required together with a low specific weight and properties of chemical inertia. The material consists of pure aluminium oxide with a small percentage of chromo oxide which gives it its characteristic red colour, which is the most visible feature of these balls in many applications as measurement and control instruments, valves and pumps. al2o3 99.99% sapphire: this material has a single crystal structure and unlike ruby is transparent. Because of its optical properties and high refraction index. Balls made of this material are currently used as chemically inert lenses.
