Industrial Applications of Bearings – A Comprehensive Guide

Do you know what “bearings,” a mechanical component, actually do? They are so essential to the machine sector that they have been dubbed the sector’s “bread and butter.” They are employed in a wide variety of machines. Still, because they operate in secrecy, most individuals not engaged in the machine sector probably have no idea what they mean when they hear the name.

Bearings come in a wide range of shapes and sizes and are an essential tribological part of many different types of machinery. In a system that may be under static or dynamic loading, they can be described as a machine element that supports/permits only a particular form of motion (limitation of degrees of freedom).

What are bearings?

Bearings are “components that aid in the rotation of objects.” Inside the equipment, they support the shaft that revolves.

Automobiles, aircraft, power generators, and other devices need bearings. Even common household items like refrigerators, vacuum cleaners, and air conditioners we use daily contain them.

The rotating shafts of the wheels, gears, turbines, rotors, etc., in those devices, are supported by bearings, enabling smoother rotation. Although bearings in industrial applications may appear straightforward mechanical components initially, they are essential to our survival.

Purpose of Bearings

Bearings primarily avoid direct metal-to-metal contact between two elements in relative motion. By doing this, friction, heat production, and, ultimately, part wear and tear are avoided. As low-friction rolling takes the place of sliding motion, it also lowers energy consumption.

Additionally, they transfer the rotating element’s load to the housing. This load could be either radial, axial, or both. A bearing, as previously mentioned, limits the freedom of motion of moving parts in specific directions.

Different Types of Bearings

There are various types of bearings, each used for a particular function and designed to support a specific type of load, like ball bearings.

Ball Bearings

A ball bearing is a specific kind of rolling-element bearing that uses balls to keep the bearings’ inner and outer moving components apart. A ball bearing’s main functions are to support radial and axial loads and lessen rotational friction. Ball bearings in industrial applications have a straightforward design, are reliable, and are simple to maintain. They come in open and sealed varieties and single and multiple-row styles. They are appropriate for high speeds since they have low frictional torque.

Ball bearings connect the shaft to the motor housing, for instance, in electrical motors when the shaft is free to rotate but the motor housing is not. They are further divided into

Applications of the ball bearings:

  • Household items: Bicycles, Washing machines, Hair dryers, Fishing rods, DVD players, and Food processors.
  • Office equipment: Fax machines, hard drives, fans, etc.

Tapered Roller Bearings

In general, taper roller bearings application can be mounted independently from the cup because the cone assembly, which consists of the inner ring with roller and cage, is removable (outer ring). Mounting is made simpler by being detachable. The appropriate rolling motion of the roller on the track surfaces of the cone and cup is ensured by the projection lines of all the taper surfaces (Cup, Cone, and Roller) meeting at a single point on the bearing axis, known as the apex point. Single and double-row taper roller bearing applications in inch and metric series are produced by NBC.

Applications Of Roller Bearing In Heavy Machinery

The roller bearing is used in the mobilization of machinery to reduce friction between moving parts. The different types of roller bearings are used in heavy-duty machinery that supports radial, axial and thrust loads. This blog discusses various applications where roller bearings are used in heavy machinery.  The bearings are made to support complex mechanical systems and their vitality can be observed in their application in a multitude of machinery. Be it automobiles, aeronautics, railways, earthmoving or agriculture, the roller bearings can be used perfectly to match the needs of different heavy-duty applications.  While referring particularly to a roller bearing, they are designed in such a way to support performance in those applications where there are large axial and radial loads. The Roller Bearings consist of the outer ring, inner ring, and a window cage which works as a holder for the rollers.

Design of Roller Bearing – Supporting Heavy Machinery

Roller Bearing helps in support the large radial and axial loads in heavy-duty machinery. This works in one direction to guide the axial loads while complimenting bearings are also used simultaneously to support the load in other directions. These types of bearings can be widely used in those conditions where the temperature may vary between -30 degrees celsius to 120 degrees Celsius.

Applications of Roller Bearings in Heavy Machinery

There can be varied types of Heavy Machinery that might require heavy-duty applications. Here are some of the applications of roller bearings in heavy machinery:
  • Wind Turbine Generators for Energy Generation – Wind Turbine generators are usually installed in high-altitude areas which require a reliable bearing solution that can operate within the high-performance wind turbines in high-speed winds. In such conditions, the tapered roller bearing and spherical roller bearings can be installed in the main shaft of the wind turbine that receives the force and can pass on the rotation to the generator.
  • Use of Roller Bearing in Agriculture Machinery – The agriculture industry also demands heavy-duty machinery as it has to deal with heavy-duty applications on a day-to-day basis. While these applications range in a multitude of high-performance tasks, the bearings must be reliable and long-lasting as they have to be used in heavy dirt and mud conditions which might also impact the bearing life. The roller bearings are one such perfect solution that can be used in varied tasks which might require heavy radial or axial loads and they can get the work done with ease. The common type of bearing used in the agriculture industry is a tapered roller bearing.
  • Construction and Heavy Machinery – The construction industry requires varied earth-moving equipment for a high range of heavy-duty tasks. While there can be varied challenges while dealing with the applications of construction, the bearings are usually exposed to excessive working conditions as machines have to be deployed for high-performance tasks. In order to meet this demand, there is a need for different types of roller bearings such as spherical roller bearings, tapered roller bearings, cylindrical roller bearings, etc. which are designed to deliver the desired performance.
  • Use of Roller Bearings in Railways – The railways are considered one of the most reliable modes of transport worldwide. While there are different systems, trains, and tracks connected over wide networks, heavy-duty machines are used to facilitate day-to-day operations. The bearings in the railway industry are used in traction motors, drive units, wheel axles, etc. While the bearings have to work in extreme conditions of carrying heavy loads and adapting to high vibrations in drive units, varied roller bearings like tapered and spherical roller bearings are also widely used to support the mechanical system. Since the railway network is now moving towards high-speed trains, the roller bearings are also designed especially for double helical gears which can work for a longer duration without the need for lubrication.
  • Use of Spherical Roller Bearings in Marine Propulsion  – Marine propulsion can be referred to as a thrust system that is used to move a boat or a giant ship. While this is also considered in the category of heavy-duty application, the diesel engine of the ship is linked to the propeller which facilitates the movement through a complex system. Here, roller bearings can be used within the shaft or different mechanical systems as there can be conditions where the bearing has to adjust to radial or axial load while also complying with the scope of heavy misalignment. These kinds of bearings are designed to handle one-directional axial load and radial load at the same time while allowing shaft misalignment.
Conclusion While heavy-duty applications use bearings within the machinery, the complex working conditions can make bearings tough to work as desired. In such cases, the different types of roller bearings are used to facilitate high-performance working conditions ensuring the reliability and longevity of bearings in multiple ways.
