533053.N12BA Bore 420 Mm, Cylindrical Roller Bearings, Four Row For Interference Fit On The Roll Neck, Machined Brass Cages
The 533053.N12BA Four-row cylindrical roller bearings is suitable for heavy machinery applications that bear huge radial loads. Classic applications include: support rolls of rolling mills, large gearboxes, heavy machine tool spindles, wind turbine spindles, ship propulsion shafts, and rotor supports for high-power compressors.
The 533053.N12BA bearing is a Cylindrical Roller Bearings, four row for interference fit on the roll neck with an inner diameter of 420 mm , an outer diameter of 580 mm, a width of 320 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears Radial, Its dynamic radial rated load is approximately 5300000 N, its static radial rated load is approximately 10400000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
533053.N12BA bearings ( 420 mm x 580 mm x 320 mm) have the advantages of Extremely high radial load capacity, high rigidity, separable design, and are therefore widely used in the metallurgical rolling mills, large gearboxes, and heavy-duty extrusion presses.

The 533053.N12BA Four-row cylindrical roller bearings mainly consist of an inner ring, an outer ring, four rows of cylindrical rollers, a cage, and a spacer. Common structures use a configuration of double outer rings (each with double raceways) and a single inner ring (with four raceways), or an interchangeable combination of inner and outer rings. Axial positioning and load distribution are achieved through the spacer.
The advantages of four-row cylindrical roller bearings are their extremely high radial load capacity, high rigidity, and the line contact between the rollers and raceways, resulting in a low coefficient of friction and allowing for high-speed operation under heavy loads. They can also be used as floating end bearings, capable of withstanding axial displacement caused by thermal expansion, and are easy to install and maintain.
