Bearing

Meaning in mechanical engineering, with examples

/ˈbɛrɪŋ/nounCore term

In mechanical engineering, bearing means: A machine element that supports a rotating or sliding part, such as a shaft, and reduces friction between the moving surfaces. Ball and roller bearings are the most common types.

In Turkish: rulman, yatak

How it is used

One of the most common words in machine design and maintenance. Bearings are selected, mounted, lubricated and replaced; engineers talk about bearing life, load rating and bearing failure. Rolling bearings are rulman in Turkish, plain bearings are kaymalı yatak or burç.

Example sentences

  1. The noise is coming from the motor bearing on the non-drive end.

  2. We replaced both bearings and checked the shaft for wear.

Common collocations

  • ball bearing
  • roller bearing
  • replace a bearing
  • bearing housing
  • bearing life
  • shaftA long, round rotating part that carries gears, pulleys or wheels and transmits power and torque from one component to another.
  • lubricationPutting oil or grease between moving surfaces, for example in bearings, gears and chains, to reduce friction, wear and heat.
  • frictionThe force that resists one surface sliding or rolling over another. It causes heat and wear, but it is also needed, for example in brakes and bolted joints.
  • vibrationA fast back-and-forth movement of a machine or structure. Too much of it can be a sign of a problem such as imbalance, misalignment or a damaged bearing.
  • wearThe gradual loss of material from a surface caused by friction, rubbing or hard particles during use, for example on bearings, gears, seals and cutting tools.
