Bearing and it's applications

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.

himself, who expressed his concern, took a humiliation,
the person who did not control his talks; he did his
abundance. [Saying OfImam Ali]

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.

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.

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

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.
