Bearings are a type of mechanical part, They are so important to the machine industry that they have been giving a important title such as the “bread and butter” of the industry. They are used in all kinds of machines including household appliances, but because they work in the shadows, most people who aren’t involved in the machine industry probably wouldn’t understand what is bearing but I will explain it in detail below.
Simplify it Bearings are parts that assist objects rotation in a machine. They support the shaft that rotates inside the machinery.Machinery that uses bearing I refer such as ac air conditioners compressor rotation of fans ,electric generators, Fans,automobiles,refrigerators, vacuum cleaners and many industries machine.
Mention back why they given the title of bread and butter because bearing support the rotating shaft of these equipment shafts , wheels,gears,turbines allowing them to rotate smoothly and basically if there is machine running there will be bearing inside.
Friction is occur between the rotating shaft and the part that supports the rotation refer to figure for example. Bearings are used between these two components.and protect the shaft and supports the rotation and also maintain the correct position of the rotation shaft.
Let examine how we reliant on bearings in our daily life. It’s difficult to imagine because we don’t often see bearing, right? take vehicle figure for example, everyone know a car and probably own one.If a car did not have bearings,The rotation would become more rough due to more friction and would consume a large amount of energy to rotate.The shaft rotation would break and tear very easily and for this reason people wouldn’t be able to drive car safely and comfortable.
