Product Description
FCD3042144 is an FCD-type Four-Row Cylindrical Roller Bearing with dimensions of 170×260×150 mm, old designation 672834, weight 30.2 kg. It features a distinctive FCD structure with double outer rings (central ribs and flat ring) and double inner rings without ribs, allowing axial displacement (floating) for thermal expansion compensation. Engineered to accommodate extremely high radial loads, it is widely used in cold rolling mills, hot rolling mills, billet mill stands, and heavy-duty metallurgical and mining equipment.
C3 radial internal clearance.
