549971 Bore 150 Mm, Tapered Roller Bearings, O-arrangement
The 549971 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 549971 bearing is a Tapered Roller Bearings, double row, in metric dimensions O-arrangement with an inner diameter of 150 mm , an outer diameter of 270 mm, a width of 172 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears Radial and axial loads, Its dynamic radial rated load is approximately 1270000 N, its static radial rated load is approximately 2320000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
549971 bearings ( 150 mm x 270 mm x 172 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.
