The NTN cylindrical roller thrust bearing is a component designed to withstand high axial loads in a single direction. Its design with cylindrical rollers and flat washers allows high load capacities and axial rigidity, ideal for applications requiring precision and durability. It is used in industrial machinery, transmission equipment and systems where axial loads are predominant.

The designation of these bearings follows NTN nomenclature: the letter K indicates a cylindrical roller thrust assembly with cage, and the numbers that follow define dimensions and series. For example, K81126 corresponds to series 811 with a 130 mm bore, while K81217 belongs to series 812 with 85 mm. Series 811, 812 and 893 differ in their load capacity and size.

These bearings are used in industries such as metallurgy, cement, mining and machine tool manufacturing. In Argentina, they are common in gearboxes, presses, cranes and material handling equipment. Their ability to withstand unidirectional axial loads makes them suitable for applications where axial space is limited and high rigidity is required. MR Accesorios Industriales sells them throughout the country.

To select the right bearing, take into account the axial load, rotation speed and environmental conditions. It is essential to ensure precise alignment between the shaft and the housing, since these bearings do not compensate for misalignment. Lubrication must be adequate, with grease or oil depending on the application, and effective sealing is recommended to prevent contamination. Assembly must be carried out with appropriate tools so as not to damage the washers.

As for equivalences, NTN cylindrical roller thrust bearings can be interchanged with those of other brands that follow the same dimensional nomenclature, such as SKF, FAG or NSK, as long as the same dimensions and load capacities are respected. It is important to verify the complete part number and tolerances. If you have any doubts, contact us with your part number and we will advise you.
