Bearings can be easily seen in the moving parts around us. It helps in reducing the rotational friction and balances both radial & axial loads.
A bearing is a rotating element which uses balls,
Rollers, needles, etc, to maintain the separation between the bearing races.
Bearing comes in several designs and it entirely depends upon the applications they are used for. They differ with the load type and their ability to manage weight. Let’s have a look at types of bearings.
Types of Bearings:
These are the most common type of bearing we use in mechanical operations. But their design is such to handle only the small amount of weight. In its function it uses two races, one contains the ball and others transmit the load through the ball.
Mostly one of the race is stationary and the other on is linked
With the rotating assembly for example shaft. Either one of the bearing races rotates and provides motion to the balls. The rotary motion of the ball tends to rotate the other bearing race.
Purpose of ball bearing
As per the engineering, Ball Bearing is a device which enables rotational or
Linear motion and reduces frictional and other stresses. By providing rotation to the device,
It reduces the surface friction between its surface and the surface it’s rolling over.
To fulfill all these functions,
Ball bearings use a relatively simple strufulfill It consists of balls with smooth metal surfaces that aid in rolling. Basically, these balls are capable of carrying the weight of the load and;
Other forces of the load’s weight which provides rotary motion.
On specifying the two types of loads it’s radial and thrust that put force on the bearing.
Radial Load puts weight on the ball bearing and in result helps the bearing to rotate due to the tension. On the other hand, the thrust load is different and in a result,
It puts stress on the bearing in a different way. On featuring an example,
The rotating bar stool is the perfect example to analyze thrust load on the ball bearings.
If we study the motion of the car tires,
It applies a radial load on the bearing while driving in the straight line. The tires roll in the forward or backward direction due to the tension and the weight of the car.
In another case when we take the car around the corner,
They subject to thrust load as now they are not moving in the radial motion. These corner forces apply weight on the side of the ball bearings.
