Silicon Nitride Ceramics (SI3N4) are a type of ceramic material with a wide range of applications due to their exceptional properties, such as high strength, low thermal expansion, and good electrical insulation. The SI3N4 ceramic ball is a popular choice for ball bearings, valve seats, and other wear parts due to its excellent mechanical properties, such as a Poisson's ratio of 0.27, a bending strength of 700 MPa, a dielectric constant of 9, a hardness of 13.9GPA, and a dielectric strength of 18-20 KV/mm. The SI3N4 ceramic ball is also known for its high corrosion resistance, making it ideal for use in harsh environments. Additionally, the SI3N4 ceramic ball is lighter than metal, making it an attractive option for applications where weight is a critical factor.
Silicone Nitride is the best ceramic material used for the ceramic bearings. Silicon nitride bearing has the density 3.20g/cm3 ,and is only half weight of zirconia bearings. More light means more speed. Can work in various chemicals.Do not need lubrication, clean, and can wash in the water.Non-magnetic and insulation. Reliable working.Without cage, Constant working in high temperature till 800 Centigrade .Outstanding long time working in low temperature till -80 Centigrade.Tolerance is as per normal bearings. Easy for assembly.

Silicon Nitride Ceramics Packaging and Shipping
Silicon nitride ceramics are typically packaged in cardboard boxes or crates to protect the product during shipping. Care should be taken to ensure that the packaging is appropriate for the weight and size of the product. Where possible, items should be wrapped in bubble wrap or foam padding to protect them further.
When shipping silicon nitride ceramics, special care should be taken to ensure that the product is securely packed. All edges should be padded with foam or bubble wrap to prevent damage during transit. It is also important to ensure that the packaging is appropriate for the weight and size of the product. For larger items, it may be necessary to use a pallet or crate to ensure that the product is properly secured and does not move during transit.
