    Product Description

    Ceramic Balls

    For many years, we have been engrossed in providing a superior range of Ceramic Balls in different technical specifications. These balls are having lower thermal expansion and increased corrosion resistance. Ideal to be used as bearings, the provided balls are manufactured with precision by pressing the mixture of ceramic powder in preform shape. The offered balls also find their extensive application in aerospace for manufacturing airframes, navigation systems and many other aerospace parts. These are also demanded for flow metering and water level sensing in various pumps. Furthermore, the provided Ceramic Balls are featured with high electrical resistance, optimum strength and lightweight.

    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 oC. 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  pumps and compressors.

    Al2o3 99, 55% 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.

    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 aluminum oxide with a small percentage of chromo oxide which gives it its characteristic red color, which is the most visible feature of these balls in many applications as measurement and control instruments, valves and pumps.
