Bearing is a mechanical element that drives relative motion to only the desired motion. It helps in reducing the friction between the moving parts. Let's dig into each type of bearing and its uses to get a wider vision.

Our project is about the Bearings and its applications

7. Friction
Friction is a force between two surfaces that are sliding, or
trying to slide, across each other. For example, when you try
to push a book along the floor, friction makes this
difficult. Friction always works in the direction opposite to the
direction in which the object is moving, or trying to move.

8. Lubrication system
The job of the lubrication system is to distribute oil to the moving
parts to reduce friction between surfaces which rub against each
other.

9. Need of bearing
Friction is bound to occur between the rotating shaft and the part that
supports the rotation. Bearings are used between these two components.
The bearings serve to reduce friction and allow for smoother rotation.
This cuts down on the amount of energy consumption.

10. Bearing
Bearings are "parts that assist objects' rotation". They support the shaft
that rotates inside the machinery. Machines that use bearings include
automobiles, airplanes, electric generators and so on

11. Types of Bearing
Bearings are a crucial tribological component of many types of machinery and exist
in a variety of forms and shapes. They can be defined as a component that
supports/permits only a specific type of motion (restriction of degrees of freedom) in
a system that may be under static or dynamic loading.
An example is a sliding door. The door cannot be lifted or removed from its place. It
only permits sliding to open it. The possible movement is restricted to sliding motion
by bearings.

Types
• Deep-Groove Ball Bearings.
• Angular Contact Ball Bearings
• Self-Aligning Ball Bearings.
• Thrust Ball Bearings.
• Spherical Roller Bearings.
• Cylindrical Roller Bearings.
• Tapered Roller Bearings.
• Needle Roller Bearings.

13. Plain Bearings
The most basic type, plain bearings consist of a flat surface without
any balls or rollers. Furniture drawers, for example, often have
plain bearings on which the individual drawers glide out and back
in. Plain bearings like flat wheels, and like other bearings, are
placed between two surfaces to reduce friction.

14. Ball Bearings
Ball bearings are characterized by their circular shape in which many small
balls are housed. They reduce friction while taking both radial and axial loads
off a moving part. According to Wikipedia, ball bearings were invented in the
late 1700s by Welsh entrepreneur Philip Vaughn who filed a patent for the
machinery component. Since then, ball bearings have become a popular
choice among manufacturers because of their high tolerance for misalignment.

15. Roller Bearings
Also known as a rolling element bearing, a roller bearing is a type of
bearing that contains the rolling elements either balls or rollers in
circular-shaped races. The races allow the rolling elements to
seamlessly roll, all while bearing the weight of the load. Roller
bearings are particularly effective at bearing heavy radial loads even
more so than ball bearings. The downside is that they aren’t
effective at bearing heavy thrust loads.

16. Fluid Bearings
Fluid bearings are designed to take the load off a moving part while also
reducing friction, but unlike the other bearings previously mentioned, they
don’t contain moving balls or rolling elements. Instead, they contain liquid
between The fluid creates a thin layer to which the moving part is exposed,
allowing it to bear the load. Most fluid bearings contain water or oil, both
of which are effective at reducing friction.

17. Magnetic Bearings
In addition to fluid bearings, magnetic bearings are another unique
alternative to traditional rolling-style bearings. Featuring powerful
magnets, they use magnetism to lift and bear loads without creating
direct contact. Magnetic bearings literally levitate moving parts into the
air, allowing for little or no friction. Of course, they only work when used
in conjunction with ferromagnetic metals.

18. Thrust Bearings
Thrust bearings are rotary bearings that are designed
specifically to support an axial load. In other words, they are
capable of rotating along with a machine's parts. Thrust
bearings, in fact, assist in the rotation of a machine's moving
parts.

22. Industrial Application
High efficiency and high precision are the most basic requirements of modern industry, and more and more
environmental protection and safety assurance issues are genetically considered. The advantages of
bearing performance are to minimize maintenance frequency and oil consumption, and to improve working
conditions by reducing the operating noise level of the machine. self-lubricating bearings have excellent
anti-friction performance even in the absence of oil, which can keep the machine in a stable state, thereby
providing an economical solution for mechanical operation

23. Robotics & Automation
Applications
With highly choreographed, programmed movement on two or more axes, robotic
bearings play a major role in the motion control aspect of this technology. The use of
high-precision bearings are an integral consideration for those tasked with designing
and maintaining these applications. Bearing life and performance demand that the
correct type, material, and lubrication are specified.

25. Features of Bearing
• Low friction, noise, and vibration
• Long service life
• Enhanced operational reliability even
under difficult conditions
• Running-in period with reduced
temperature peaks
• Separable and interchangeable
components help to facilitate mounting,
dismounting and maintenance

26. Example:
The bell crank fits over a 100-mm-diameter shaft which is fixed and cannot rotate. The
horizontal force T is applied to maintain equilibrium of the crank under the action of
the vertical force P = 100 N. Determine the maximum and minimum values which T
may have without causing the crank to rotate in either direction. The coefficient of
static friction between the shaft and the bearing surface of the crank is 0.20.

29. Example
Assume that a 20-mm-diameter rivet joins the plates that are
each 110 mm wide. The allowable stresses are 120 MPa for
bearing in the plate material and 60 Mpa for shearing of rivet.
Determine (a) the minimum thickness of each plate; and (b) the
largest average tensile stress in the plates.
