Morphology
The meaning 'a bearing designed to support thrust or axial loads' is directly composed from 'thrust' (axial/propulsive force) plus 'bearing' (a part that allows rotation), so the definition is predictable from the parts. This straightforward noun–noun technical compound follows regular English composition patterns and would be inferable to a B1 learner who knows both constituent words.
Etymology
The noun thrust bearing comes from what it does: thrust means a strong 'push' along a shaft and a bearing is a part that supports moving pieces. Imagine a rod pushing forward and a round support catching that push, so a thrust bearing is a bearing made to take that 'push'.
