Four row cylindrical roller bearings can carry much heavier radial load and shock load. They have higher precision and can be applied in the equipment which runs with high rotational speed. Grinding the surface of raceway and roller at same time after the inner ring is pressed on roller neck, it favors the improvement of rolling precision and the free adjustment of mounting clearance of bearings. These bearings are mostly applied to the working roller and backup roller of rolling mills and some other cases.
FC: double outer rings, single inner ring, and inner without flange.
FCD: double outer rings, double inner rings, and inner ring without flange.
FCDP: double outer rings, only have center flange, but with loose rib, double inner ring, inner without flange.
