Definition
Meaning and Definition
A specific type of bearing designed to support axial loads (forces parallel to the shaft), preventing movement along the shaft's axis.
In a metaphorical sense, it can refer to any component or mechanism that absorbs or manages a direct, forward-pushing force or pressure within a system.
Dialectal Variation

FAQ
Frequently Asked Questions
A 'regular' (typically radial) bearing supports loads perpendicular to the shaft (radial loads). A thrust bearing specifically supports loads parallel to the shaft (axial or thrust loads).
They are critical in applications with high axial loads: automotive clutches (release bearings), ship propellers, helicopter rotors, turbine engines, water pumps, and gearboxes.
It is standardly written as two separate words: 'thrust bearing'.
Yes. Some bearing types, like angular contact ball bearings or tapered roller bearings, are designed to handle combined loads (both radial and axial). A pure 'thrust bearing' is optimized primarily for axial load.
A specific type of bearing designed to support axial loads (forces parallel to the shaft), preventing movement along the shaft's axis.
Thrust bearing is usually technical / engineering in register.
Thrust bearing: in British English it is pronounced /ˈθrʌst ˌbeə.rɪŋ/, and in American English it is pronounced /ˈθrʌst ˌber.ɪŋ/. Tap the audio buttons above to hear it.

Learning
Memory Aids
Mnemonic
Imagine a rocket's THRUST pushing it forward. The THRUST BEARING is the part inside that handles that pushing force, 'bearing' the load.
Conceptual Metaphor
A BRAKE FOR FORWARD MOTION (within a rotating system). It allows rotation but stops/controls linear push.
