Product Description
FCD3042149 is a high-capacity FCD-type Four-Row Cylindrical Roller Bearing with dimensions 180×250×130 mm and weight 20.7 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 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.
Key Features
