The spherical roller thrust bearing is a component designed to withstand very high axial loads while at the same time allowing a certain misalignment between shaft and housing. Its design with spherical rollers and a spherical seat raceway gives it that self-aligning capability. It is used in applications where the load is primarily axial and mounting conditions are not perfect, such as presses, cranes, ship propellers or large gearboxes. MR Accesorios Industriales sells this NSK line in Buenos Aires, Argentina.

The designation of this series is read from its letters and numbers. The EM suffix indicates a one-piece machined brass cage, inner ring guided, which provides greater strength and heat dissipation. The number preceding it, as in 29488EM, identifies the size and load capacity of the bearing. The series is named by its letters and examples: EM series. To correctly interpret each code, it is best to consult the manufacturer or a specialist.

Typical applications of spherical roller thrust bearings include equipment where the axial load is dominant and there is a risk of shaft deflection: hydraulic presses, high-tonnage cranes, rotary tables, marine propellers, large-size speed reducers and overhead crane supports. In Argentine industry they are found in steel plants, cement plants, mining operations and in the shipbuilding sector. Also in mills and crushers where loads are severe and alignment conditions are difficult.

To correctly select a spherical roller thrust bearing, take into account the magnitude and direction of the axial load, the rotation speed and the environmental conditions. It is essential to verify lubrication: these bearings are usually lubricated with grease or oil and require an adequate film to prevent premature wear. Mounting must ensure that the spherical raceway of the outer ring seats correctly in the housing. Initial alignment is less critical than in other types, but it is advisable to check the perpendicularity of the shaft with respect to the base.

As for equivalences and interchangeability, spherical roller thrust bearings from different brands may differ in dimensions and capacities. It is not enough for the code to be similar: bore diameter, outer diameter, height and permissible load must be compared. If you have the code from another brand, we can help you find the appropriate NSK equivalent. It is always advisable to verify tolerances and internal clearance before replacing one bearing with another from a different manufacturer.
