YDTech™ manufacturers of steel steel balls (Chrome 52100, Stainless 440C & tungsten), Ceramic Si3N4, ZrO2 balls and tungsten, titanium balls.

one option to consider when enhanced ball performance is a concern is titanium carbide coated (TiC) balls. TiC balls typically offer As a premier manufacturer with decades of metallurgical and ceramic engineering experience, we pride ourselves on delivering unmatched quality across the entire spectrum of spherical components. Our dual expertise in both high-performance steel balls and advanced ceramic balls positions us as the singular, reliable partner for industries ranging from aerospace and automotive to chemical processing and medical devices.

The Steel Ball Portfolio: Strength, Durability, and Versatility Our steel ball manufacturing capabilities cover the most demanding grades, ensuring we have the right material for every application.

52100 Chrome Steel (AISI 52100/GCr15): This is the undisputed industry standard for high-load bearing applications. With its high carbon and chromium content, 52100 offers exceptional hardness (up to HRC 62–65), outstanding wear resistance, and excellent dimensional stability. Our 52100 balls are the backbone of precision bearings, linear guides, and automotive drivetrains, engineered for millions of cycles under extreme stress.

Stainless Steel 440C & 420: Corrosion resistance meets high hardness. Our 440C stainless steel balls combine the wear characteristics of bearing steel with superior resistance to rust and mild acids, making them ideal for aerospace actuators, medical instruments, and high-performance pumps. With a hardness of HRC 58–62, they are exceptionally durable in high-friction environments. For applications requiring moderate corrosion resistance and high toughness, we offer 420 stainless steel balls, a cost-effective solution for valve and seal applications.

Stainless Steel 316: For environments where corrosion is the primary enemy, our 316 stainless steel balls are the ultimate choice. The addition of molybdenum provides outstanding resistance to chloride corrosion, pitting, and chemical attack. These balls are extensively utilized in marine hardware, food processing equipment, pharmaceutical mixing vessels, and chemical pumps where hygiene and non-reactivity are critical.

The Advanced Ceramic Ball Portfolio: Beyond the Limits of Metal While steel excels in strength, there are environments where metal simply falls short. This is where our ceramic ball technology takes center stage. We manufacture premium ceramic balls using isostatic pressing and precision grinding techniques to achieve surface finishes that rival the finest steel products.

Silicon Nitride (Si₃N₄): This is the premier choice for high-speed, high-temperature, and electrically demanding applications. Our Si₃N₄ balls are lightweight—only 60% the weight of steel—which drastically reduces centrifugal force and bearing friction at high RPMs. They exhibit exceptional thermal shock resistance and retain their strength at temperatures up to 800°C. Consequently, they are the standard for hybrid ceramic bearings, electric vehicle (EV) motor supports, and high-speed spindle applications.

Zirconia (ZrO₂) – Y-TZP: When extreme toughness, corrosion resistance, and non-magnetic properties are required, our Zirconia balls are unmatched. With fracture toughness nearly twice that of Silicon Nitride, ZrO₂ balls are highly resistant to chipping and impact. They are impervious to most harsh chemicals and acids, making them indispensable for chemical mixing, paint dispersion, and pharmaceutical milling. Furthermore, their non-conductive nature allows them to serve as excellent insulating components in electronic devices.
