Bearings,as important components in contemporary mechanical equipment,mainly support the mechanical rotating body,which can reduce the friction coefficient during its movement and ensure its rotation accuracy.
Double row cylindrical roller bearing - mostly used in metal, and aluminum rolling mills;
higher rolling efficiency with inner rings remained onto
the rolls during processing;
608 silicon nitrideballs ceramic bearing with size 8*22*7mm ,this bearing are produce with ceramic Si3N4 and PEEK Seals which can working at temperature at 800 degree .
