Bearing box – Definition & Meaning

A bearing box is a mechanical device used to support rotating shafts and reduce friction between moving parts. It is an essential component of many types of machinery, including engines, turbines, and pumps. In this article, we will explore the definition and meaning of bearing box, its origin, associations, synonyms, antonyms, and example sentences.

Definitions

A bearing box is a housing that contains one or more bearings and is used to support a rotating shaft. It provides a stable platform for the bearings to operate and protects them from dirt, dust, and other contaminants. The bearing box can be made of various materials, including metal, plastic, or composite materials.

Origin

The bearing box has been used for centuries in various forms. The ancient Greeks and Romans used wooden bearings to support the axles of their chariots. In the 18th century, the French engineer Nicolas-Joseph Cugnot developed the first steam-powered vehicle, which used metal bearings to support the wheels. Since then, the design and construction of bearing boxes have evolved significantly, with modern materials and manufacturing techniques enabling greater precision and durability.

Meaning in different dictionaries

According to the Oxford English Dictionary, a bearing box is “a metal or wooden box in which a bearing is mounted.” Merriam-Webster defines it as “a housing for a bearing that supports a rotating shaft.” The Cambridge Dictionary describes it as “a container for a bearing that is used to support a rotating shaft and reduce friction.”

Associations

The bearing box is closely associated with the field of mechanical engineering and is used in a wide range of applications, from small household appliances to large industrial machinery. It is also associated with precision manufacturing and requires careful design and construction to ensure optimal performance.

Synonyms
