Used to reduce the friction between two objects, a ball bearing is a small ceramic or metal ball. To the Roman Empire, The concept of the bearing dates back. However, to Leonardo da Vinci, the practical design is credited. In his helicopter designs, he used this ideal.
For the use of his axle assembly that used ball bearings, Philip Vaughan was patented in 1971, which was a carriage builder. To Jules Surrey, the first patent on ball bearings was given.
The thin wall ball bearing design is very simple. At least two ring shape tracks are there. While the other track rotates, one of the tracks is a permanent feature. Lowering the rotational friction between objects the small balls having rotation are inside the track.
A little more complex is the manufacturing of bearings. First, in a machine that has two circular plates, the metal wire is placed. These halves come together to form a rough-looking metal ball with a great amount of force.
Removing the flashing from the ball, the ball is then placed in another machine. To the requested size, this same machine will then ground the ball. To be shined and polished, the ball goes through the machine.
The ball bearing design as well as the technology has advanced. Fast popularity is being gained by the Ceramic ball bearings. With ceramic balls, they combine the steel track system. From solid silicon nitride, the ceramic balls are made. As their steel counterparts, they run longer and are faster.
As compared to the steel bearings, they are also lighter, stronger and smoother. They reduce vibration and noise and also run at cooler temperatures while in use. In mills and high-speed machines, Ceramic bearings are used. In their precision instruments, Doctors also rely on this system.
In everyday life, thin section ball bearing of China is used. In everything from a computer's hard drive to roller skates, they are found. To keep their products working and to keep their machinery running, the industrial sector relies on them. For this system, Technology advances have found more needs and at the same time, the system is improved as a whole.
