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.

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.

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.
