FCDP6084300 Four Row Cylindrical Roller Bearing

The FCDP6084300 is a heavy-duty four-row cylindrical roller bearing specially developed for metallurgical rolling mill backup rolls. It features 300mm bore, 420mm outer diameter and 300mm width, offering ultra-high radial load capacity and rigidity. Its separable structure permits axial floating displacement, perfectly adapted for hot rolling mills, cold rolling mills and billet mills.

Key Features

• Four-row roller structure for maximum radial load capacity
• Machined pin-type steel cage, stable performance under heavy shock load
• Fully separable inner and outer rings, convenient installation and maintenance
• C3 radial internal clearance for high-temperature mill working conditions
• Open construction, cylindrical bore
• Optional precision grades: P0 / P4 / P5

Applications

FCDP6084300 is mainly applied to rolling mill backup rolls in hot rolling, cold rolling and billet rolling production lines. Also suitable for other heavy metallurgical equipment, large mining machinery and heavy-duty roller conveyors. It reduces raceway wear, improves operational stability and extends service life under continuous heavy load.
