544145 Bore 558.8 Mm, Tapered Roller Bearings, Double Row For Loose Fit On The Roll Neck
The 544145 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 544145 bearing is a Tapered Roller Bearings, double row for loose fit on the roll neck with an inner diameter of 558.8 mm , an outer diameter of 736.6 mm, a width of 196.85 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears Radial and axial loads, its static radial rated load is approximately 10800000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
544145 bearings ( 558.8 mm x 736.6 mm x 196.85 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.
