SI3N4 Ceramic Ball With 3800 MPa Compressive Strength And 7 MPa
Fracture Toughness
Product Description:
Silicon Nitride Ceramics are a superior choice for a wide range of
industrial applications due to their excellent thermal and
electrical properties, high strength-to-weight ratio, and superior
wear resistance. These ceramics are composed of the unique and
highly stable silicon nitride (Si3N4) compound, which can be formed
into a variety of shapes and sizes. Our Silicon Nitride Ceramics
are renowned for their outstanding performance, with a density of
3.2 g/cm3, fracture toughness of 7 MPa, dielectric constant of 9,
hardness of 13.9 GPa, and Poisson's ratio of 0.27. These unique
properties make Silicon Nitride Ceramics the ideal choice for a
variety of applications, including SI3N4 ceramic balls used in
bearings, valves, and other industrial components.
Similarly silicon nitride ceramic bearings have high-temperature
resistance, corrosion resistance, wear resistance, oilless
self-lubricating, anti-magnetic, insulation, high-speed and other
features. si3n4 ceramic bearing is widely used in aviation,
aerospace, military, petroleum, chemical, metallurgy, automobiles,
electricity, medical equipment and other extremely harsh
environments and conditions.
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.
