What is a Ball Bearing and Define its best 5 types?

Bearing is a necessary part of a machine.  Ball Bearing is related to roller bearing. Now it is used in every machine to reduce friction between two moving parts. There are so many bearings is used in machines as per need. If you don’t know about bearing then it is the right place. I have already discussed bearing in a content. If you know about then click here. 

 Today I discuss Ball Bearing. Here I discuss its definition, types and it’s applications. Before discussing all first know what is it?

What is a Ball Bearing?

It is related to roller bearing. It fulfills mainly 3 functions. One function is to reduce friction between two moving parts. The second is load capacity. The third is the positions of moving machine parts.  

It uses rolling element balls to maintain the gap. The gap is between the two bearing races. To reduce friction between two moving parts is the main intention of a ball bearing.  

Types of Ball Bearing:

The classification of Ball Bearing given below:

Angular Contact Bearings:  

It is manufactured to work under combined radial and axial loads. 

Axial Bearings:  

It is manufactured to work under the force applied parallel to the bearing axis and thrust load. 

Deep-Groove Bearings:

It is manufactured to carry both radial and light axial loads. 

Linear Bearings: 

It is manufactured to permit movement in one direction along a linear axis. 

Self-aligning Bearings:

These bearings carry two sets of balls that are self-aligning. Self-aligning ball bearings carry both radial and low axial loads. 

High-Speed Angular Contact Bearings:  

It is another type of ball bearing in high-speed angular contact. Here high-speed bearings are manufactured to handle high RPM. 

Ball-Bearing size and materials: 

According to the used bearing size differently. The width of the bearing depends on the object. The diameter of the outside race and inside races is different. It allows for compact designs.  

There are many materials used to manufacture bearings. It depends on the application. A large number of Ball Bearings are manufactured from steel material. Also stainless steel and ceramic materials are used to manufacture it. 

Why is the Ball Bearing used in the machine? 

It is used to reduce rotational friction. It supports radial and axial loads. It obtains this by using two races to contain the balls. It delivers the loads through the balls. When one race of bearing rotates the balls also rotate. Because rolling balls are rolling. Rolling balls have an insufficient coefficient of friction. It is held if two flat surfaces were sliding against each other. 
Most Ball Bearings are used in machinery. It includes moving parts such as computer fans, hard disk drives, and skateboards. 
It is used in machines. It has a lot of moving work. Bearings decrease the friction so the machine can work smoothly. The sliding friction transformed into rolling friction. It is much less and power excess is reduced. 

it has many advantages but there are some disadvantages. 

 Such as: 

 They are uncomfortable with shock loading. 

They have no vibrations and are noisy. 

Their applications may be limited own to solid races. 

How Ball Bearing Functions?

To connect two machine parts to move relative to one another in a way. The motion is small than the frictional resistance.   It is the function of this bearing. One part of the machine is a rotating shaft and the other is fixed in several applications. 

There are mainly three parts of this bearing. The parts are two races, two groves, and steel rolling element balls. The races are different diameters but the same width. The smaller race is fitting inside the outer race. The small has a groove on the outside surface of the machine part. The large race also has a groove. The groove is on the inside surface of a machine part. The steel balls have fulfilled the space between the two races. The balls are freely restrained and separated.

How do Ball Bearings reduce friction? 

it works on the principle. The principle is sliding friction is greater than rolling friction. It helps to reduce friction between two surfaces in contact. It maintains separation between the bearing races. They allow the smallest surface contact between two surfaces. 

Applications of Ball Bearing: 

There is some application given below as per need. 

Angular Contact Bearing: 

This bearing is used in gearboxes, pumps, motors, clutches, and other high-speed applications. They are also used in machine tools, material handling, steel mills, and wind energy. 

Deep Groove Bearing:

This bearing is used in mechanical engineering tasks.  It is used in gearbox, motors, pumps, and industrial machines. 

Self-aligning Bearing: 

This bearing is used in fan applications and textile segments. 

Thrust Bearing:

This bearing is used in aerospace applications and automotive applications. It is also used in the main and tail rotor blade of helicopters. It is used in radio antennas to reduce the load. 

Conclusion about Ball Bearing: 

Every mechanical field employee and worker knows the bearing necessary. The use of bearing is different as per need. It is necessary to reduce friction in machine parts. Here I discuss all about this topic. I think I give useful basic information about Ball Bearing in my article. If my article is useful for you than give your valuable feedback. Your feedback motivate me.
