521084 Bore 812.8 Mm, Tapered Roller Bearings, Double Row, Inch Dimensions
The 521084 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 521084 bearing is a Tapered Roller Bearings, double row, in inch dimensions O-arrangement with an inner diameter of 812.8 mm , an outer diameter of 1016 mm, a width of 190.5 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears Radial and axial loads, its static radial rated load is approximately 11200000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
521084 bearings ( 812.8 mm x 1016 mm x 190.5 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.
