2. The main characteristics of the product
• ZrO2 Zirconia Ceramic Material
The use of zirconia ceramic in our bearings provides several outstanding properties. It offers exceptional hardness, which significantly reduces the risk of wear and deformation, even under heavy loads and high speeds. The ceramic material also exhibits excellent corrosion resistance, making it suitable for use in harsh environments where traditional metal bearings may fail. Additionally, zirconia ceramic has a low density, contributing to a reduction in the overall weight of the bearing and the rotating system, which is beneficial for applications where weight is a critical factor, such as in aerospace.
• High-Speed Capability
These bearings are specifically designed to operate at extremely high speeds. The combination of the ceramic material's thermal stability and the precision-engineered ball and raceway geometry allows for efficient heat dissipation and minimal friction. This enables the bearings to maintain their performance and integrity even during prolonged high-speed operation, reducing the risk of overheating and premature failure. The high-speed capabilities of our bearings make them ideal for applications such as high-speed spindles in machine tools and turbine engines.
• Precision Angular Contact Design
The angular contact design of the bearings allows them to handle both axial and radial loads with great precision. This design ensures that the loads are evenly distributed across the balls and raceways, minimizing stress concentrations and maximizing the bearing's load-carrying capacity. The precise angular contact also contributes to the overall stability and accuracy of the rotating system, making these bearings essential for applications that require tight tolerances and precise motion control, such as in precision machining and optical equipment.
• Low Friction and Smooth Operation
Thanks to the high-quality ceramic material and the precision manufacturing process, our bearings operate with extremely low friction. This not only reduces power consumption but also results in smooth and quiet operation. The low friction characteristics also contribute to a longer service life by minimizing wear on the bearing components. In applications where vibration and noise reduction are crucial, such as in electronics manufacturing and high-precision instruments • Enhanced Thermal Stability
Zirconia ceramic has excellent thermal stability, which means that the bearing's performance remains consistent even in the presence of significant temperature changes. This is essential for applications where the operating conditions involve rapid heating and cooling, such as in high-speed machining processes. The thermal stability of our bearings helps to maintain the dimensional accuracy of the components and ensures reliable operation over a wide range of temperatures.

4. Product use instructions
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. If the bearing shows signs of significant wear, it should be replaced promptly to prevent further damage to the equipment. Use a micrometer or other precision measurement tools to accurately assess the bearing's condition.
