533780 bearings ( 950 mm x 1360 mm x 880 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 533780 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.
