Product Description

Product Description

 

Our High Performance Silicon Nitride Ceramic Balls stand as the pinnacle of excellence for bearing applications. Thanks to the superior attributes of silicon nitride ceramics, these balls surpass traditional steel materials in countless ways. Experience unmatched benefits such as exceptional mechanical strength, minimal wear, and innate self-lubrication. These balls boast low density and exhibit remarkable resistance to corrosion, alongside excellent electrical insulation properties. Specifically engineered for challenging environments, they are the preferred choice for high-speed and super-speed bearings, precision bearings operating in a vacuum, and applications demanding resilience across fluctuating temperatures. Beyond bearings, our Silicon Nitride Ceramic Balls serve crucial roles as valve and measurement balls in chemical, high-temperature, and metering pumps.

 

 

 

Product Parameters

 

Main Features: Discover the epitome of toughness with our balls' high hardness and unparalleled wear resistance. They demonstrate robust resistance to strong acids and alkalis, making them suitable for use even in seawater environments. Their nonmagnetic nature and electrical insulation properties extend utility into magnetic fields. With a low density, they reduce centrifugal forces during rotation. The thermal expansion coefficient is a mere 1/4 of GCrls, allowing high-temperature applications. Application Fields:1. Precision machinery thrives in extreme environments with high temperatures, vacuums, corrosive elements, and high-speed demands; 2. Perfect for the foundry industry, enduring high temperatures and robust environments; 3. Essential in aluminum casting parts and consumables; 4. Integral to the PV industry, precision electronics, and aviation sectors; 5. Pioneering advancements in the automobile and new energy industries.
