What is FALSE regarding thrust bearings?

Thrust bearings are specifically designed to support axial loads, which are forces that act parallel to the axis of rotation. They are essential components in machinery where they maintain the position of a rotating shaft in relation to housing and absorb axial forces.

The statement that thrust bearings are designed to allow lateral movement is false because their primary function is to restrict movement along the axial direction, providing stability to the shaft and preventing it from moving laterally. They effectively prevent unwanted axial motion, contributing to the overall stability of the assembly.

In contrast, other options correctly describe various characteristics of thrust bearings. They certainly help stabilize rotating shafts by ensuring that any axial loads are effectively absorbed. Additionally, thrust bearings act as a barrier to unwanted axial movement, which is critical for the performance and longevity of rotating machinery.
