Definition

Meaning and Definition

A type of alloy, often containing tin, lead, copper, and antimony, used to line bearings to reduce friction and wear.

More broadly, any metal or alloy (e.g., Babbitt metal, white metal) specifically engineered for use in sliding or rolling bearings due to its low-friction properties, embeddability, and conformability.

Dialectal Variation

British vs American Usage

Differences

Virtually no lexical difference. Both use 'antifriction metal' or the more common 'bearing metal'. 'Babbitt metal' (or 'babbitt') is equally common in both variants.

Connotations

None beyond technical specificity.

Frequency

Extremely low frequency in general language. Used identically within relevant technical fields in both regions.

Examples

Examples of “antifriction metal” in a Sentence

verb

British English

  • The bearing surface was antifrictioned with a layer of white metal.
  • They will antifriction the journal bearing.

American English

  • The bushing was antifrictioned with Babbitt.
  • We need to antifriction this component.

adjective

British English

Usage

Meaning in Context

Business

Virtually never used. Might appear in procurement lists for industrial machinery parts.

Academic

Used in specialized papers and textbooks on mechanical engineering, tribology, or metallurgy.

Everyday

Completely unknown. A layperson would say 'bearing material' or not know the term.

Technical

The primary and almost exclusive context. Refers to the specific material specification in engineering designs, maintenance manuals, and parts catalogues.

Watch out

Common Mistakes When Using “antifriction metal”

  • Misspelling as 'anti-friction metal' (hyphenated) or 'antifriction metal' (as one word is standard).
  • Using it as a countable noun (e.g., 'an antifriction metal')—it's usually uncountable, referring to the material.
  • Confusing it with the entire bearing assembly rather than just the lining material.

FAQ

Frequently Asked Questions

Yes, Babbitt metal is the most common and famous type of antifriction or bearing metal, typically based on tin, lead, or antimony.

Its primary and almost exclusive application is in plain bearings (bushings, thrust washers). Its properties make it unsuitable for structural components.

Softness allows it to embed small abrasive particles and conform to small irregularities in the harder shaft, preventing scoring and further wear.

Yes, though often supplemented or replaced by polymer composites or advanced coatings in some applications, traditional antifriction metals like Babbitt are still widely used in heavy machinery, turbines, and automotive engines.

A type of alloy, often containing tin, lead, copper, and antimony, used to line bearings to reduce friction and wear.

Antifriction metal is usually specialized/technical (engineering, mechanics, metallurgy) in register.
