526251 Bore 381 Mm, Tapered Roller Bearings, Double Row, Inch Dimensions
The 526251 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 526251 bearing is a Tapered Roller Bearings, double row, in inch dimensions O-arrangement with an inner diameter of 381 mm , an outer diameter of 508 mm, a width of 139.7 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears Radial and axial loads, its static radial rated load is approximately 3200000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
526251 bearings ( 381 mm x 508 mm x 139.7 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.
