Field of Application
一）High temperature field
The transmit roller of high temperature furnaces:SiC ceramic retains strength and harden-ss nearly up to 1000℃,but bearing steel hardness drops above 120℃
二）Aviation and air***ce fields
The coefficient of thermal expiation of SiC is 0.0000032/k but that of bearing steel is 0.00001/k,that are nearly in the ration of 1 to 4. Thereford SiC cermic bearings are mo-re stable and reliable in a temperature changeable condition.
三）Main shaft of machine tools
The SiC ceramic has double the hardness of bearing steel,and 1/3 modulus of elasticitylarger than that of bearing steel,We can found that the elastic deformation of SiC is small under an identical loading.
四）Chemical machinery,food industry and marine industry
The ceramic bearings can solve corrosion problems Ex. acid ,alkali ,salt and so on.
五）High vacuum field
In high vacuum field people take the advantage of self-lubrication of ceramic bearings to replace the bearing in order to prevent vacuum from lubrication contamination.
六）Strong magnetic environment
n a strong magnetic environment the metal powder which is produced from wear of steel bearing,adheres the surfaces of rolling element and race way and causes flanking in aduance and increasing noise. The solution to this problem is also using ceramic bearing.
七）Toys ,roller skates,model navigation and motor-driven toys
It is the price factor of ceramic bearing that limits its wide use in the world.So up to no-w most applications of ceramic bearing are merely in high speed,high precision mechanism,in addition the hybrid construction of ceramic bearing,that is ceramic ball with steel inn-er ring and outer ring,is most adopted.Owing to adopting net shaping technology the using of above mentioned spheres but also of roller skates,model navigation and motor-driven toys.
Speciality
Ceramic materials are noted for their characters of high strength in high temperature,high rigidity,corrosion resistance,high temperature resistance, |
