ball bearing
C1Technical / Industrial
Definition
Meaning
A bearing in which the load is carried by a number of hardened steel balls that roll between two grooved, concentric metal rings.
One of these hardened steel balls itself, typically used as an individual component or as ammunition in certain projectile weapons. Metaphorically, can refer to something that facilitates smooth movement or function.
Linguistics
Semantic Notes
Primarily a technical, countable noun. In engineering contexts, it refers to the complete assembly. In manufacturing or informal contexts, it can refer to the individual ball component.

Learning
Memory Aids
Mnemonic
BALL (a sphere) + BEARING (something that supports and reduces friction) = steel balls that bear a load and make things roll smoothly.
Conceptual Metaphor
A SYSTEM/ORGANIZATION IS A MACHINE: 'The new manager is the ball bearing that makes the whole department run smoothly.'
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'шаровая опора' which is a specific automotive term (ball joint). The correct general term is 'шарикоподшипник'.
- Do not confuse with 'подшипник качения' (rolling bearing) which is the hypernym; 'ball bearing' is a specific type.
Common Mistakes
- Using non-countable form: 'The wheel needs ball bearing.' (Correct: '...a ball bearing' or '...ball bearings.')
- Confusing 'ball bearing' (the assembly) with just 'bearing' (which can be many types).

Frequently Asked Questions
It is a compound noun, typically written as two separate words.
Ball bearings use spherical balls as rolling elements, suitable for lighter loads and higher speeds. Roller bearings use cylindrical rollers, handling heavier radial loads.
Not precisely. 'Bearing' is a broad category. 'Ball bearing' is a specific type. In casual conversation about common appliances, the meaning might be understood, but technically it's inaccurate.
Yes, in contexts like ammunition for ball-bearing guns or as a loose component, the individual ball can be called a ball bearing. In engineering, the term usually refers to the entire assembly.
