2. The main characteristics of the product
• Exceptional High-Temperature Resistance The silicon nitride ceramic material used in our bearings is specifically formulated to withstand temperatures as high as 1200℃. This remarkable property allows them to operate reliably in environments where other bearings would simply melt or degrade. The ceramic's inherent stability at extreme temperatures ensures that the bearing's structural integrity and performance are maintained, even under prolonged exposure to intense heat. This makes our bearings ideal for applications such as industrial furnaces, kilns, and high-temperature turbines.
• Outstanding Insulation Properties These bearings offer excellent electrical insulation capabilities, thanks to the non-conductive nature of silicon nitride ceramic. This insulation is crucial in applications where electrical conductivity could pose a safety hazard or interfere with the operation of sensitive equipment. In power plants, for example, the bearings prevent electrical current from passing through the rotating components, reducing the risk of short circuits and ensuring the smooth and safe operation of generators and motors. The insulation also helps to protect against electromagnetic interference, enhancing the performance of electronic components in proximity to the bearings.
• Precision-Machined Cage Design The accompanying cage is meticulously designed and precision-machined to enhance the overall performance and durability of the bearing. The cage not only provides proper spacing and guidance for the rolling elements but also contributes to the bearing's load-carrying capacity. It is engineered to withstand the high temperatures and mechanical stresses associated with the application, ensuring that the balls or rollers move smoothly and evenly within the raceways. The cage's design also aids in reducing friction and wear, further extending the life of the bearing.
• Low Friction and Wear Resistance Silicon nitride ceramic has a naturally low coefficient of friction, which means that our bearings operate with minimal resistance. This not only reduces energy consumption but also results in less wear and tear on the bearing components. The smooth operation of the bearings also contributes to a quieter and more efficient performance, making them suitable for applications where noise reduction and precision are important, such as in high-speed machinery and precision instruments.
• Chemical Resistance and Corrosion Protection In addition to their high-temperature and insulation properties, our bearings exhibit excellent resistance to a wide range of chemicals and corrosive substances. This makes them suitable for use in harsh industrial environments where exposure to acids, alkalis, and other corrosive agents is common. The chemical resistance of the silicon nitride ceramic helps to prevent the degradation of the bearing surfaces, ensuring long-term reliability and performance.

1、Installation Before installation, ensure that the work area is clean and free from any debris or contaminants. Use clean, lint-free gloves to handle the bearing to prevent fingerprints and other residues from affecting its performance. Inspect the bearing for any signs of damage or defects, such as scratches, dents, or irregularities on the raceways or balls. If any issues are detected, do not install the bearing and contact the supplier for a replacement. When installing the bearing onto the shaft, use a gentle and even pressure to ensure proper seating. Avoid using excessive force, as this could cause damage to the bearing or the shaft. If necessary, use a suitable installation tool, such as a press fit sleeve or a bearing installer, to ensure accurate and damage-free installation. Ensure that the bearing is properly aligned with the shaft and the housing. Any misalignment can lead to increased wear and reduced bearing life. Use alignment tools or precision jigs to achieve the correct alignment, especially in applications where precision is critical.
2、Operation Start the equipment gradually and allow the bearing to warm up to its operating temperature. Avoid sudden starts and stops, as this can cause excessive stress on the bearing and lead to premature failure. Monitor the operating temperature, vibration, and noise levels of the bearing during operation. Any significant changes in these parameters could indicate a problem, such as insufficient lubrication, misalignment, or overloading. If detected, take immediate action to address the issue and prevent further damage. Ensure that the equipment is operating within the specified load and speed limits of the bearing. Exceeding these limits can significantly reduce the bearing's lifespan and may result in catastrophic failure. Refer to the product documentation or consult the supplier for the recommended operating parameters.
3、Maintenance Regularly clean the bearing and its surrounding area to remove any dirt, dust, or other contaminants that could accumulate during operation. Use a suitable cleaning solvent and a soft brush or cloth to gently wipe the bearing surfaces. Avoid using harsh chemicals or abrasive materials that could damage the bearing. Check the lubrication level and quality of the bearing regularly. The frequency of lubrication depends on the operating conditions and the type of lubricant used. Use a high-quality lubricant that is suitable for the application and the operating environment. Follow the manufacturer's recommendations for lubricant application methods and quantities. Periodically inspect the bearing for signs of wear, such as pitting, spalling, or increased clearance.
