803312 Bore 406.4 Mm, Tapered Roller Thrust Bearings, Double Row For Work Rolls
The 803312 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 803312 bearing is a Tapered Roller Thrust Bearings, double row for work rolls with an inner diameter of 406.4 mm , an outer diameter of 546.1 mm, a width of 138.113 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 1160000 N, its static radial rated load is approximately 2850000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
803312 bearings ( 406.4 mm x 546.1 mm x 138.113 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.
