Precision balls

Ceramic balls

The main characteristics of ceramic balls are high temperature and resistance to corrosion, together with excellent mechanical resistance. They do not require lubrication.
Ceramic balls

SILICON NITRIDE

(SI3N4)
It is the most used ceramic material because has a high resistance to corrosion, working efficiently until a temperature up to +1200ºC. It presents extreme hardness and can be manufactured in high precision. It has a weight 60% lower than steel. This material does not require lubrication. It is used mainly in the aerospace industry.

ALUMINA OXIDE

(AL2O3)
It presents a bigger resistance to temperature that the silicon nitride, as well as a high resistance to corrosion, resisting most of the corrosive agents except hydrofluoric and hydrochloric acid.

ZIRCONIA OXIDE

(ZRO2)
Material with a very low electric conductivity, presents high flexibility. Small sizes (between 0,2 - 3,3 mm) are used for pigments production due to its high resistance to wear.

RUBY

Frequently asked questions

What are the main characteristics of ceramic balls?

They are balls with high hardness and wear resistance. Their operating temperature is very high, reaching up to 1600 °C in the case of alumina oxide balls. One of their main characteristics is their corrosion resistance, even when in contact with strong acids, as is the case with silicon nitride balls.

What types of ceramic balls can LUIS APARICIO, S.L. supply?

We offer high and medium precision ceramic balls made of alumina oxide, silicon nitride, zirconium oxide, ruby, and sapphire. They are soldby units for industrial applications.

What are the applications of precision ceramic balls?

Special bearings, pumps and valves in corrosive environments, measuring instruments, and flow meters. They are used in the aerospace, oil, chemical, and electronics industries.

What sizes of ceramic balls can be supplied?

It is possible to supply various diameters of balls ranging from 1 to 40 mm in alumina oxide, silicon nitride, and zirconium oxide. For larger diameters and for ruby and sapphire balls, availability should be inquired.

What is the process for requesting a quote?

Please send an email to luisaparicio@luisapariciosl.com specifying the diameter, quantity, and required precision grade or tolerances.
