If you have worked with machines or know a little about mechanics, probably you are aware of the importance of the different types of mechanical bearings, which are used in machinery. Electricity is one of the major costs involved in the operations of a machine and controlling such expenses becomes a priority of the businesses. Thus, such machinery in employee parts like the mechanical bearings to reduce the friction within the machine and make it efficient.
Although they remain invisible to the user, but day to day machinery like cars and computers also use bearings. Multiple bearings rule over the market, differentiating in sizes and various uses. According to their function, they could be constructed in different kinds of metals or even in plastic. Their abilities to reduce friction and survive loads depends upon the usage of the bearings and their type. Let’s explore some of the most commonly used ones.
If you have seen the mechanics of a clock, you could have noticed a jewel bearing, which is used in watches as it reduces the friction between the working automatic parts of the watch. A metal spindle is what sets its pivot hole apart from the other bearings.
The Magnetic Bearing
Sometimes the functions of these bearings might also be considered magical. They perform the task provided to them by using the power of magnetic field around them. Thus, they might not come into the physical contact with the actual parts of the machine. Majority of the times, the bearings use electromagnetism instead of the natural magnets, thus for a smooth functioning of the machines continuous electricity is necessary.
As the parts work on the basis of magnetism and there is no physical contact, there is no need for lubricants and regular upkeep of such parts. These bearings are usually used in turbines and generators.
The Plain Bearing
If you are looking for a part which will not only be able to take a lot of load but also would be able to last long, plain bearing is the thing you are looking for. These bearings can be identified as lack of the rolling capabilities.
A normal bearing might not be able to tolerate high load and vibrations of the particular moving parts of a machine, thus usage of certain liquids and lubricants might help the machine to work at high speeds with greater effectiveness and precision. A fluid-dynamic bearing creates a wedge of lubricants, thus is able to dodge any physical contact by rotating at high speeds.
On the other hand, fluids like water and oil might be used as lubricants in hydraulic bearings which usually use an external pump for this purpose.
Some of the ball bearings decrease the resistance offered by the moving parts by helping the parts to slide and roll. These type of bearings are relatively weak, as they might get deformed when extra pressure is applied to them as they are directly in contact with the moving parts.
