802081.H122AE Bore 317.5 Mm, Tapered Roller Bearings, Four Row With Integrated Seals For Rolling Mills
The 802081.H122AE Four-row tapered roller bearings are suitable for applications involving heavy combined loads. Classic applications include rolling mill work rolls, heavy machine tool spindles, mining crushers, oil drilling rig turntables, large wind turbine spindles, and shaft positioning ends of ship propulsion systems.
The 802081.H122AE bearing is a Tapered Roller Bearings, four row with integrated seals for Rolling Mills with an inner diameter of 317.5 mm , an outer diameter of 422.275 mm, a width of 269.875 mm. Bearing steel rings, Bearing steel rolling mlement. It primarily bears Radial and axial loads, Its dynamic radial rated load is approximately 3050000 N, its static radial rated load is approximately 6550000 N. Double Sealed (integrated seals) type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
802081.H122AE bearings ( 317.5 mm x 422.275 mm x 269.875 mm) have the advantages of It can withstand extremely high radial loads and bidirectional axial loads, has a compact structure, and is highly rigid, making it suitable for heavy-duty impact conditions, and are therefore widely used in the Metallurgical rolling mills, large gearboxes, heavy mining machinery, oil drilling equipment.

The 802081.H122AE Four-row tapered roller bearings typically consist of two double-raceway outer rings, two single-raceway inner rings, four rows of tapered rollers, a cage, and a spacer. The inner and outer rings and rollers are designed in metric or imperial units. The axial clearance or preload can be precisely adjusted by grinding the spacer.
The advantage of four-row tapered roller bearings is that they can withstand huge radial loads and bidirectional axial loads at the same time. They have extremely high overall rigidity and excellent load-bearing capacity, making them suitable for use as fixed ends to achieve precise axial positioning. However, their limiting speed is relatively lower than that of cylindrical roller bearings.
