512704A Bore 190.5 Mm, Tapered Roller Bearings, Double Row, Inch Dimensions
The 512704A 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 512704A bearing is a Tapered Roller Bearings, double row, in inch dimensions O-arrangement with an inner diameter of 190.5 mm , an outer diameter of 266.7 mm, a width of 103.188 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears Radial and axial loads, its static radial rated load is approximately 1500000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
512704A bearings ( 190.5 mm x 266.7 mm x 103.188 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.
