The NTN cylindrical roller thrust bearing is a component designed to support high axial loads in one direction. Its construction with cylindrical rollers and washers allows high load capacities and axial rigidity. It is used in applications where precision and durability are critical, such as gearboxes, machine tool spindles and lifting equipment. MR Accesorios Industriales sells this series.

The series designation is interpreted by its base number: the first digits indicate the type of cylindrical roller thrust bearing and the following ones the size. The usual suffixes, such as WS, identify the shaft washer, which in these assemblies is usually supplied separately. For example, WS81100 corresponds to the shaft washer for bearing 81100. Knowing this nomenclature makes it easier to select the correct component according to the available space and the load to be supported.

These bearings are used in industries such as metallurgy, cement, mining and machine tools. In Argentina, they are common in presses, extruders, cranes and earthmoving equipment. Their ability to support pure axial loads makes them ideal for applications where axial space is limited and high rigidity is required. They are also found in gearboxes and milling machine spindles, where axial precision is essential for surface finish.

To select the right bearing, it is crucial to consider the axial load, the rotation speed and the environmental conditions. The mounting must guarantee precise alignment between the shaft and the housing; any misalignment reduces service life. Lubrication can be grease or oil, depending on speed and temperature. In applications with contaminants, additional seals should be evaluated. The WS washer must be mounted with the correct fit to prevent slipping.

NTN cylindrical roller thrust bearings are interchangeable with those of other brands that follow the same dimension standard. When replacing a bearing, it is important to verify the critical dimensions: shaft diameter, outer diameter and height. The NTN series usually corresponds to similar series from other manufacturers, but compatibility should always be confirmed. MR Accesorios Industriales can advise you on the correct equivalent according to the original code.
