Meaning and Definition
A simple mechanical component, such as a sleeve or bushing, where one surface slides over another without rolling elements.
A type of bearing that operates on the principle of sliding friction between a stationary and a moving surface, typically requiring lubrication to reduce wear. Common in applications where simplicity, cost-effectiveness, and high load capacity in one direction are priorities.

FAQ
Frequently Asked Questions
Yes, in many contexts, 'bushing' is a common synonym, particularly for a thin, sleeve-type plain bearing.
Plain bearings are often preferred for their simplicity, lower cost, higher load capacity in one direction, better shock load absorption, and quieter operation.
Typically, it is higher friction and wear, especially during start-up and shut-down, which necessitates continuous lubrication and more frequent maintenance.
Some are designed as 'dry' or self-lubricating bearings using materials like PTFE or graphite. However, most metal plain bearings require a lubricant to function properly and prevent seizure.

Mnemonic
Think of a 'plain' donut – it's simple, with no fancy sprinkles or filling, just like a plain bearing has no rolling balls or complex parts.
Conceptual Metaphor
A SLIDING DOOR MECHANISM: Emphasizes the direct, sliding interface between two surfaces, much like a door slides in its track.
