Thrust Bearing Purpose: The Ultimate Guide to Unlocking Performance and Longevity
Thrust bearings are essential components in a wide range of industrial applications, including high-speed motors, gearboxes, and pumps. Their purpose is to support axial loads, which are forces that act parallel to the shaft, and prevent lateral movement while allowing for axial rotation. By doing so, they ensure the smooth and efficient operation of these systems.
