The Anti-corrosion Silicon Nitride Ceramic Si3N4 Small & Miniature Ball Bearing series includes models 693, 623, 694, 624, 695, 625, 696, 626, 697, 627, 698, 628, and 699. These bearings are designed for applications requiring high durability, corrosion resistance, and reliable performance in harsh environments. Made from silicon nitride (Si3N4), a advanced ceramic material, they offer superior resistance to chemicals, acids, and alkalis. This makes them ideal for use in marine, chemical processing, and medical equipment where exposure to corrosive substances is common.

The material properties of Si3N4 ensure these bearings operate smoothly under extreme conditions. They withstand temperatures up to 800°C without losing structural integrity. Unlike steel bearings, they do not rust or degrade when exposed to moisture or aggressive media. Their lightweight design reduces rotational inertia, improving efficiency in high-speed applications. Electrical insulation properties prevent current leakage, making them suitable for electronic or electrically sensitive systems.

These bearings require minimal maintenance due to their self-lubricating capabilities. They perform well in vacuum environments and are unaffected by temperature fluctuations. Common applications include precision instruments, aerospace components, laboratory equipment, and food processing machinery. The non-magnetic nature of silicon nitride ensures compatibility with MRI machines and other devices sensitive to magnetic interference.

Available in open or shielded configurations, the bearings come in standard sizes matching common miniature bearing dimensions. Precision grades ensure tight tolerances for smooth rotation and reduced vibration. Customization options include special coatings or modified internal clearances for specific operational needs.

Key specifications include high load capacity, low thermal expansion, and a hardness rating exceeding most metals. The absence of metal components eliminates the risk of galvanic corrosion. These bearings are tested for longevity under continuous stress, ensuring reliable service in critical systems. Compatibility with standard mounting methods allows easy integration into existing machinery.

The product is stocked in multiple quantities, with bulk orders supported for industrial clients. Technical support is available for selecting the correct model based on load, speed, and environmental factors. Packaging options include anti-static containers to prevent contamination during shipping. Lead times vary based on configuration requirements.
