577881 Bore 260 Mm, Tapered Roller Bearings, Double Row For Vertical Rolls In Universal Roll Stands
The 577881 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 577881 bearing is a Tapered Roller Bearings, double row for vertical rolls in universal roll stands with an inner diameter of 260 mm , an outer diameter of 400 mm, a width of 196 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears Radial and axial loads, its static radial rated load is approximately 4650000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
577881 bearings ( 260 mm x 400 mm x 196 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.
