511990 Bore 300 Mm, Tapered Roller Bearings, O-arrangement
The 511990 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 511990 bearing is a Tapered Roller Bearings, double row, in metric dimensions O-arrangement with an inner diameter of 300 mm , an outer diameter of 420 mm, a width of 159 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears Radial and axial loads, Its dynamic radial rated load is approximately 1560000 N, its static radial rated load is approximately 3800000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
511990 bearings ( 300 mm x 420 mm x 159 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.
