803981 Bore 325 Mm, Tapered Roller Bearings, Double Row With Extended Cone
The 803981 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 803981 bearing is a Tapered Roller Bearings, double row with extended cone with an inner diameter of 325 mm , an outer diameter of 469.9 mm, a width of 182.563 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears Radial and axial loads, its static radial rated load is approximately 6400000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
803981 bearings ( 325 mm x 469.9 mm x 182.563 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.
