Cojinete (ES/CO/CL)

A technical term for bearing used predominantly in Spain, Colombia, and Chile, covering both rolling-element bearings (cojinete de rodamiento/bolas/rodillos) and plain/journal bearings (cojinete de deslizamiento/friccion). In Spain: "cojinete" is the standard engineering term for any bearing type. In Colombia and Chile: "cojinete" is used alongside "rodamiento" (for rolling-element bearings specifically). Important distinction: in some LATAM countries, "cojinete" specifically means a plain/sleeve/journal bearing (the older bearing technology using a sliding contact surface), while "rodamiento" means a rolling-element bearing (modern ball or roller type). This distinction matters technically: a "cojinete de bronce" is a bronze bush/sleeve bearing, while a "rodamiento de bolas" is a ball bearing — fundamentally different products. In Mexico: "cojinete" is less common; "balero" (colloquial) and "rodamiento" (technical) are preferred. For technical documentation: use "rodamiento" for rolling-element bearings and "cojinete de deslizamiento" or "buje" for plain bearings to avoid ambiguity across all LATAM markets.

Full definition

The term 'cojinete' refers to a type of bearing commonly used in Spain, Colombia, and Chile. In Spain, it is the standard term for any bearing type, encompassing both rolling-element bearings, known as 'cojinetes de rodamiento,' and plain or journal bearings, referred to as 'cojinetes de deslizamiento' or 'cojinetes de fricción.' This terminology can lead to confusion in Latin America, where the term 'cojinete' is sometimes specifically associated with plain bearings, while 'rodamiento' is reserved for rolling-element bearings. Therefore, the distinction is essential for accurate communication in engineering and procurement contexts. For instance, a 'cojinete de bronce' indicates a bronze bush or sleeve bearing, whereas a 'rodamiento de bolas' refers to a ball bearing, which operates on entirely different principles and applications. In technical documentation, it is advisable to use 'rodamiento' for rolling-element bearings and 'cojinete de deslizamiento' or 'buje' for plain bearings to maintain clarity across all Latin American markets, particularly where regional variations in terminology could lead to misunderstandings. In Mexico, the term 'cojinete' is less frequently used, with 'balero' being the colloquial term and 'rodamiento' being the more technically appropriate choice. This linguistic diversity underscores the importance of using precise terminology in industrial applications to avoid costly errors in bearing selection and maintenance.

What you need to know

  • What you need to know: 'Cojinete' is a generic term for bearings in Spain, encompassing both rolling and plain types.
  • In Colombia and Chile, 'cojinete' often refers to plain bearings, while 'rodamiento' denotes rolling-element bearings.
  • In Mexico, 'balero' is the colloquial term, with 'rodamiento' preferred for rolling-element applications.
  • Technical documentation should specify 'cojinete de deslizamiento' for plain bearings to avoid ambiguity.

Industrial applications

  • 1Used in automotive applications for both rolling-element bearings in engines and plain bearings in suspension systems.
  • 2Applied in machinery where rotational motion is needed, such as electric motors using rolling bearings.
  • 3Utilized in manufacturing equipment for sliding applications, where plain bearings reduce friction and wear.

Common mistakes

  • ✕Confusing 'cojinete' with 'rodamiento,' leading to incorrect bearing specifications.
  • ✕Using regional terms interchangeably without considering local engineering standards.
  • ✕Neglecting to specify the type of bearing needed, which can result in equipment failure.
💡

Pro tip

Always clarify the type of bearing required in technical documents to ensure precise communication and reduce the risk of errors.
