Product Description
FCD4466230 is a high-capacity FCD-type Four-Row Cylindrical Roller Bearing with dimensions 220×330×230 mm and weight 68.5 kg. Its distinctive FCD structure features double outer rings with central ribs and a flat ring, plus double inner rings without ribs, enabling axial displacement (floating) to accommodate thermal expansion. This bearing is interchangeable with SKF 314889/VJ202 and FAG 541452, and is engineered to handle extreme radial loads in cold and hot rolling mills, billet mill stands, and heavy-duty metallurgical and mining equipment.
Supplied with C3 radial internal clearance for optimal performance.
