578647 Bore 479.425 Mm, Tapered Roller Bearings, Double Row, Inch Dimensions, Machined Steel Cages
The 578647 Rolling mill bearings are mainly suitable for applications such as floating ends that bear medium to heavy radial loads and need to accommodate shaft thermal expansion, or roll necks that need to bear combined radial and axial loads, as well as gear drives.
The 578647 bearing is a Tapered Roller Bearings, double row, in inch dimensions O-arrangement with an inner diameter of 479.425 mm , an outer diameter of 679.45 mm, a width of 276.225 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears Radial and axial loads, its static radial rated load is approximately 11800000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
578647 bearings ( 479.425 mm x 679.45 mm x 276.225 mm) have the advantages of Extremely high load-bearing capacity and rigidity, and are therefore widely used in the Hot rolling, cold rolling, and wire rod mills.
