Bearings are fundamental pieces of equipment, the main objective of this component is to facilitate the desired movement, minimizing friction and improving machine performance.

Bearings are classified according to the type of operation, the movements allowed or the directions of loads (forces) applied to the parts. Bearing applications cover virtually all industries that employ mobile or rotating components and equipment.

Wortice offers bearing maintenance and repairs, in addition to the manufacture of this component itself, and its main use in the power generation sector is in steam turbines, gearboxes and power generators.

What are <strong>Bearings?</strong>

What are Bearings?

Bearings are devices that allow movement in a fixed direction between two parts, usually rotational or linear movement. Bearings can be grouped by the way they work. There are several types of bearings, however, the most common are rolling bearings and plain bearings

 Bearings are mechanical components developed to allow the support of a shaft while it rotates, in order to always keep it in its original position.

The factors that influence the choice of bearings are:

  • Load capacity
  • Lifespan
  • Available space
  • Working speed
  • Precision
  • Noise level
  • Stiffness
  • Axial displacement
  • Misalignment
  • Easy assembly
  • Easy disassembly

Types of Bearings

Rolling Bearing

When the bearing has a rolling, it’s called a rolling bearing, due to the rolling friction.

In rolling bearings, the moving surfaces are separated by balls or rollers, and then, friction rub is replaced by rolling friction.

As the contact area is small and the stresses are high, the rotating parts of the bearings are made of hard, high-strength materials.

The biggest advantage of rolling bearings is that the friction at start-up is almost equal to the operating friction in contrast to the initial metal-to-metal friction of friction bearings.

Bearings can be classified as radial or axial.

Slip Bearing

When the bearing has a bushing, it’s called a plain bearing, due to the type of friction, which in this case is sliding.

Sleeve bearings have a bushing that has the function of receiving direct friction with the shaft surface. According to the type of effort, we can classify the bearings into:

  • Bearings for radial loads
  • Thrust bearings

Bushings are generally cylindrical and have a hole to allow the lubricant to pass through. They may also have slots to improve the passage of the lubricant.

Equipment that can be used

In a thermoelectric plant, bearings can be used in the following equipment:

  • Steam turbines
  • gearboxes
  • Power generators
Babbitt bearing<strong> (patent metal)</strong>

Babbitt bearing (patent metal)

Babbitt metal can be one of several alloys used as a bearing surface in plain bearings It’s a white, soft, non-ferrous alloy that is used to provide a bearing surface.

Bearings are used in engines to support moving mechanical parts and protect them from frictional degradation. Babbitt metal also has properties that help reduce friction, which makes it a good material for use in a plain bearing. Babbitt metal is soft and can be easily damaged if not treated properly.

This would make it look unsuitable for use as a bearing surface, however the alloy structure is made up of small hard crystals, which are dispersed in a softer alloy matrix. This means that as the bearing wears out, the harder crystal is exposed and a path for the lubricant is provided.

The bearings Babbitt 's work by providing a low coefficient of friction, achieved primarily by two means.

First, there is the fact that the bearing itself has a low coefficient of friction, so even without lubrication, a Babbitt bearing will have much less friction than another metal such as steel or cast iron.

However, by adding lubrication, Babbitt bearings can have a significantly low coefficient of friction, even lower than ball bearings.
