Silicon nitride ceramic balls have been developed to outperform traditional steel bearings in terms of lightness, corrosion resistance and high heat capacity – not to mention non-magnetism.
Electric motor bearings benefit from electrical insulation properties to prevent electric arcing and extend their service lives, thus saving money in bearing replacement costs.
Precision silicon nitride ceramic balls can be produced through either hot isostatic pressing (HIP) or gas pressure sintering (GPS), and come in various sizes for dental drills to large wind turbines.
Low Friction Coefficient
Silicon nitride balls boast lower densities than steel, making them significantly lighter and decreasing centrifugal forces and friction during high-speed rotations. Their lower density enables them to retain their size and shape even as temperatures change, protecting against damage or deformation and making them ideal for aerospace and other high performance applications.
Ceramic materials’ hardiness enables them to resist wear and tear better, and their limited expansion upon heat makes them suitable for applications requiring extreme temperature conditions.
Silicon nitride ceramics’ low friction coefficient helps minimize energy losses and maximize efficiency in mechanical systems, thus reducing heat generation during operation and prolonging bearing lifespan. Silicon nitride also acts as an excellent electrical insulator, diverting current away from metal components to extend their lives and allow them to perform in harsher environments more easily.
High Temperature Resistance
Silicon nitride ceramics possess superior high temperature resistance, maintaining strength and hardness up to 800 degC without suffering damage. Furthermore, these resilient balls can operate in environments with strong acids, alkalis, seawater or chemical inertness without becoming compromised – as well as their chemical inertness which makes them resistant against any corrosion caused by harmful substances like acids or alkalis. Lastly, silicon nitride balls make ideal bearing applications due to their thermal stability, low coefficient of thermal expansion rate and thermal shock resistance which allows rapid changes without alteration in shape or size alteration compared to traditional bearing balls made of ceramic balls or bearing applications.
Silicon nitride ceramic balls are lightweight, which helps reduce centrifugal forces and rolling friction on bearing surfaces, thus prolonging service life. Their nonmagnetic and electrically insulating properties make them an excellent choice for electric motors, hybrid bearings and engine components, and precision rods made from silicon nitride are widely used across aerospace, medicine, machine tools pumps valves hybrid bearings hybrid engine components and precision rods with ground and polished surfaces for uniform size, spherical accuracy as well as resistance against corrosion oxidation wear resistance and wear resistance.

Resistance to Corrosion
Silicon nitride (SiN) ceramics are exceptionally corrosion-resistant, boasting excellent stability in oxidizing environments and boasting outstanding mechanical strength, destructive toughness, high modulus properties and exceptional mechanical strength compared to other technical ceramics. Furthermore, SiN ceramics possess superior tensile strengths that resist elongation as well as yielding and rupturing at elevated transverse stresses.
SiN ceramics have many characteristics that make them exceptionally long-lived and low maintenance costs, reducing maintenance requirements compared to other materials. Furthermore, their lower energy requirements enable systems to function more efficiently while their low coefficient of friction reduces energy loss and produces less heat in bearings thereby increasing efficiency and prolonging equipment lifetime.
Ceramic balls are lightweight, which allows systems to perform better while saving space and reducing overall system weight. Furthermore, ceramic balls are non-magnetic and electrically insulating – perfect for applications including aerospace, industrial, military, medical and auto industry applications such as rotors, probes, master balls and calibration tools in machine design as well as 3D coordinate measuring machines. Their high temperature resistance makes them an excellent choice for pumps, compressors, dental drills and vacuum pumps.
Thermodynamically Stable
Silicon nitride ceramic precision balls can be utilized in applications requiring bearings with exceptional reliability, longevity and life expectancy. Their properties include high hardness, low coefficient of friction/lubricity/corrosion resistance. Furthermore, these balls can withstand high temperatures while remaining anti-magnetic; additionally they are impervious to hydrofluoric acid, making them suitable for many other chemicals as well.
Low density high-performance bearings reduce centrifugal forces, making them suitable for high-speed applications. Furthermore, their thermal expansion coefficient is typically lower than most metals, mitigating any impact from temperature changes on size or shape changes of balls.
Silicon nitride ceramics are manufactured using cutting-edge production processes such as spray drying granulation, cold isostatic pressing, net size molding and GPS HIP sintering followed by high-efficiency grinding to reach G5 precision (GB/T308 2002) and grade 1 material quality in their final products.
Medical Applications
Silicon nitride’s unique material properties make it an excellent choice for medical applications, including dental implants, spinal fusion devices and knee replacement devices. Ceramic silicon nitride products can even be radiolucent to allow plain radiographs to detect them clearly while their high mechanical strength and fracture toughness make them suitable for bone replacements that must withstand significant loads and stress levels.
Our ceramic balls are constructed from fully dense sintered Si3N4 Silicon Nitride (SSN), an advanced ceramic with superior mechanical and thermal properties, making it perfect for systems and machines exposed to high pressure, temperature and vibration.
Silicon nitride ceramics feature strong tensile strengths that enable them to withstand significant transverse stresses without cracking or breaking, as well as superior flexural strengths to withstand yielding and rupture at elevated transverse stresses. Their moderate thermal conductivity and low coefficient of thermal expansion reduce cooling costs significantly, making these ceramics suitable for aerospace and industrial applications at higher speeds.
