Advantages And Disadvantages Of Silicon Carbide Bearings:

Advantages of silicon carbide bearings:

It has excellent chemical resistance, wear resistance, high temperature resistance, high mechanical strength, good self-lubricating property, high temperature creep, low coefficient of friction, higher thermal conductivity and low coefficient of thermal expansion.

Disadvantages of silicon carbide bearings:

1, as the bearing of the shielding electric pump, because it also has a small coefficient of thermal expansion (sic thermal expansion coefficient is stainless steel 1/4), when the medium temperature is high, and with the stainless steel parts with it to produce gaps or interference resulting in bearing damage. 2, the material is brittle, the fracture toughness is the stainless steel 1/50, the material is more brittle, by the impact force action easy to break, especially the angular place.
