Ceramic ball bearings SI3N4
The Ceramic ball bearings SI3N4 from Shanghai Lits Import & Export Co., Ltd. are precision components made from silicon nitride, a material known for its hardness and resistance to wear. These bearings are designed for high-speed applications where low friction and long service life are critical, such as in aerospace, robotics, and precision machinery. The supplier specifies silicon nitride (Si3N4) as the base material, with inherent properties like high temperature resistance and lightweight construction compared to steel alternatives.
Silicon nitride bearings typically offer superior corrosion resistance and electrical insulation, making them suitable for use in harsh or chemically aggressive environments. The standard composition for Si3N4 ceramic bearings includes a minimum purity of 99.5%, with typical density around 3.2 g/cm³ and hardness exceeding 1500 HV. These bearings are often used in applications where steel bearings fail due to thermal expansion or chemical exposure, and they maintain dimensional stability under extreme conditions.
Industries that rely on these bearings include semiconductor manufacturing, medical devices, and high-performance motors. Buyers often source them for their ability to operate at speeds above 1,000,000 DN (bore diameter x RPM), with typical dynamic load ratings ranging from 5 to 20 kN depending on size. The supplier, based in Shanghai, offers these bearings for bulk export, with logistics details to be confirmed directly for lead times, Incoterms, and packaging specifications.

Sourcing Ceramic ball bearings SI3N4 from Shanghai Lits Import & Export Co., Ltd. - China Import Guide
Before ordering, verify the exact material composition and purity levels of the Si3N4 bearings, as these directly impact performance in high-speed or high-temperature applications. Request certification documents for the material, such as ISO or industry-specific standards, to ensure compliance with your technical requirements. Confirm whether the supplier can provide third-party test reports for hardness, density, and load ratings.
Discuss logistics terms, including Incoterms like FOB or CIF, to clarify responsibilities for shipping, insurance, and customs clearance. Lead times can vary based on order volume, so request a realistic timeline for delivery and confirm whether the supplier can accommodate urgent shipments. Packaging details, such as individual wrapping or bulk crating, should also be agreed upon to prevent damage during transit.
Inspect the bearings upon arrival for dimensional accuracy, surface finish, and absence of defects like cracks or chips. Use a calibrated micrometer to check bore diameter, outer diameter, and width against the specified tolerances. Request a certificate of conformity to confirm the bearings meet the stated specifications, and consider arranging an independent inspection if the order is large or critical to your operations.
