548243 Bore 288.925 Mm, Tapered Roller Bearings, Double Row With Extended Cone
The 548243 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 548243 bearing is a Tapered Roller Bearings, double row with extended cone with an inner diameter of 288.925 mm , an outer diameter of 406.4 mm, a width of 165.1 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears Radial and axial loads, its static radial rated load is approximately 4750000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
548243 bearings ( 288.925 mm x 406.4 mm x 165.1 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.
