549970 Bore 105 Mm, Tapered Roller Bearings, O-arrangement
The 549970 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 549970 bearing is a Tapered Roller Bearings, double row, in metric dimensions O-arrangement with an inner diameter of 105 mm , an outer diameter of 190 mm, a width of 118 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears Radial and axial loads, Its dynamic radial rated load is approximately 655000 N, its static radial rated load is approximately 1100000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
549970 bearings ( 105 mm x 190 mm x 118 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.
