What are bearings? Bearings are "parts that help an object to rotate". They support the shaft that rotates inside a machine. Machines that use bearings include cars, aircraft, generators and so on. They are even used in household appliances that we use every day, such as refrigerators, hoovers and air conditioners. Bearings support the rotating shafts of wheels, gears, turbines, rotors, etc. in these machines so that they can rotate more smoothly. In this way, machines of all kinds require a large number of shafts to rotate, which means that bearings are almost always used, so much so that they have been called the "bread and butter of the mechanical industry". At first glance, bearings may seem like simple mechanical parts, but without them we would not be able to survive. The role of bearings So what role do bearings actually play in keeping machines running smoothly? They fulfil two main functions. Function 1: Reducing friction for smoother rotation Friction is b...

  "Bearings" are a type of mechanical part, but do you know what they do? They are, in fact, so fundamental to the machine industry that they have been called the industry's "bread and butter". They are used in all sorts of machines, but because they do their work in the shadows, most people who aren't involved in the machine industry probably hear the word and think "What's that?"   So for this, the inaugural "Bearing Column", we are going to explain the absolute basics of bearings, and provide a brief explanation of the functions they serve. 1. So just what are bearings? 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. They are even used in household appliances that we all use every day, such as refrigerators, vacuum cleaners and air-conditioners.   Bearings support th...
