67790DW.720 Bore 177.8 Mm, Tapered Roller Bearings, Double Row For Loose Fit On The Roll Neck
The 67790DW.720 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 67790DW.720 bearing is a Tapered Roller Bearings, double row for loose fit on the roll neck with an inner diameter of 177.8 mm , an outer diameter of 247.65 mm, a width of 90.488 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears Radial and axial loads, its static radial rated load is approximately 1460000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
67790DW.720 bearings ( 177.8 mm x 247.65 mm x 90.488 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.
