Shanghai J&C new int'l trading Co., ltd is a company which are proffessinal produce and export bearing and ceramic product to all over the world.
Our main product varies from stainless bearings, Chrome steel bearings, ceramic bearings, silicon nitride, zirconia, alumina ceramic balls for bearings and other purposes.
Si3N4 is considered as a candidate material for high speed hybrid bearing in ultra high-speed precision spindles of machine tools or in jet turbines of aircraft due to its desirable properties such as lower density, harder hardness, higher elastic modulus, thermal and chemical stability compared to the traditional steel ball for bearing and higher fracture toughness than the other advanced ceramics so that the hybrid ceramic bearing with Si3N4 has outstanding advantages of a longer bearing service life (2-5 times of steel bearing), higher running speed (up to 5 x 106 DN), favorable failure mode (failure of Si3N4 is generally by spalling like steel ball due to its higher toughness rather than by catastrophic failure like the other lower toughness ceramics), higher overall accuracy and quality, higher temperature capability, and non-magnetic property etc. Silicon nitride has seen wide usage in the bearing industry in the last 10 years. |
