Which type of axial thrust bearing is commonly used?

The tilting pad type axial thrust bearing is commonly utilized due to its ability to handle large axial loads with minimal friction. This design features multiple pads that can tilt, allowing for a greater area of contact with the shaft as it rotates. This tilting action not only enhances load distribution, reducing localized wear but also facilitates better lubrication and cooling, which is crucial for maintaining performance and longevity in high-load applications.

Other types of bearings, such as roller, ball, and fixed bearing types, can be used in specific applications but may not offer the same level of efficiency and adaptability under axial loads as the tilting pad design. Roller bearings, while capable of supporting significant loads, do not exhibit the same tilting capability, which limits their effectiveness in certain orientations. Ball bearings may also experience higher stress concentrations under axial loading compared to tilting pad designs. Fixed bearings typically restrict movement in one direction and do not provide the necessary adaptability needed for dynamic loads found in many industrial applications. Thus, the tilting pad type stands out as the preferred choice for axial thrust applications.
