What is a Bearing?

What is a bearing? What is its designated function? Bearings are mechanical components that are designed to ensure motion only occurs in the desired direction. The main purpose of a bearing is to support such a motion and to reduce friction between the moving parts.

While some bearings allow for free linear movements, others allow for rotation around a fixed axis or even prevent certain motions by ensuring that normal forces are more controlled or limited. When looking for the right bearings on the market for your application, you will find that they are typically classified according to the type of movement that they support or limit.

There are many bearings available on the market, with the simplest being designed to fit into a machine or machine part in order to operate. There are complicated and sophisticated bearings on the market too. These are designed to support precise movements, and are manufactured and operated with state-of-the-art machinery and equipment. There are 6 types of common bearings on the market that you will encounter and each has its own service life expectancy attached, as follows:

  • Plain bearings – the life expectancy of these bearings is determined by the material used in their construction.
  • Rolling-element bearings – the life expectancy of these bearings is determined by various aspects, including load, maintenance, temperature, lubrication, contamination, handling, installation and so on.
  • Jewel bearings – these can also enjoy a long life expectancy depending on the material that they are constructed from.
  • Fluid bearings – these can have indefinite service lives without signs of wear.
  • Magnetic bearings – these can also have indefinite service lives without showing signs of wear.
  • Flexure bearings – life expectancy of these bearings can be indefinite if they are manufactured from the right material and are correctly used.
