A bearing is a machine element that allows parts rotating in different directions relative to each other to make this movement with minimum friction, allowing them to reach higher speeds with less power expenditure. Basically, bearings, which are formed by the combination of 4 different main parts, are used in the bearing of shafts that can be produced in different sizes for different sizes of bearings and shafts. Since bearings are precision machine elements, their production requires high technology and meticulousness. In addition, the right bearing must be selected to get high efficiency from bearings. You can see bearings in many machines that work or are operated in circular or axial motion. In the picture below, you will see the picture used inside the mast system. You can see a simple bearing that is formed by intertwining an inner ring and an outer ring inside the pole system. In order for these rings to rotate freely within each other, there is a series of rollers placed in the intermediate part. It is vital to the quality and longevity of the bearing that these rollers are all very aligned and properly positioned with the same size and smoothness. The most technologically advanced factories are naturally able to produce the highest quality bearings. What makes bearings important is to ensure that the motion that needs to be transmitted is transmitted with the least possible friction, that is, with the least compromise on power.
