509391 Bore 470 Mm, Tapered Roller Thrust Bearings Double Acting, With Spacer, Brass Cage
The 509391 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 509391 bearing is a Tapered Roller Thrust Bearings double acting, with spacer with an inner diameter of 470 mm , an outer diameter of 720 mm, a width of 200 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears axial, Its dynamic radial rated load is approximately 3400000 N, its static radial rated load is approximately 19300000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
509391 bearings ( 470 mm x 720 mm x 200 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.
