Bearings for Steam Turbine

Wortice works with the manufacture and maintenance of bearings for steam turbines according to the requirements of each customer. Bearings for steam turbines are components of a steam turbine used for fixed support of shafts.

We offer maintenance and manufacturing services for parts and components for several types of bearings for steam turbines, such as:

  • Sleeve bearings for steam turbines
  • Roller bearings for steam turbines

What are <strong>Steam Turbine Bearings?</strong>

What are Steam Turbine Bearings?

Steam turbine bearings are components that support a shaft and allow for normally rotational or linear motion.

Bearings for steam turbines can be grouped by the way they work. There are several types of bearings for steam turbines, however, the most common are roller bearings for steam turbines and sleeve bearings for steam turbines

We can say that the bearings for steam turbines 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 for steam turbines are:

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

Types of Bearings for Steam Turbine

Rolling Bearing for Steam Turbine

When the bearing has a rolling, it’s called a rolling bearing, and due to the rolling friction in the rolling bearings, the moving surfaces are separated by balls or rollers and then, the friction rub replaced by the 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 for steam turbines is that the friction at start-up is small and practically the same as during operation, in contrast to the high initial metal-on-metal friction of plain bearings. According to the type of effort, we can classify the bearings into:

  • Roller bearings for steam turbines for radial loads

Sliding Bearing for Steam Turbine

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:

  • Sleeve bearings for steam turbines for radial loads
  • Sleeve bearings for steam turbines for axial loads

Bushings are generally cylindrical and made of patent metal, and have a hole to allow the lubricating oil to pass through. They may also have slots to improve the passage of the lubricant.
