578243 Bore 420 Mm, Tapered Roller Thrust Bearings, Double Row For Work Rolls
The 578243 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 578243 bearing is a Tapered Roller Thrust Bearings, double row for work rolls with an inner diameter of 420 mm , an outer diameter of 540 mm, a width of 112 mm. inner ring made of case hardening steel rings, Bearing steel rolling mlement. It primarily bears Radial and axial loads, Its dynamic radial rated load is approximately 1140000 N, its static radial rated load is approximately 3450000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
578243 bearings ( 420 mm x 540 mm x 112 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.
