A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.
The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other.
Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races.
Although roller bearings had been developed since ancient times, the first modern recorded patent on ball bearings was awarded to Philip Vaughan, a Welsh inventor and ironmaster who created the first design for a ball bearing in Carmarthen in 1794. His was the first modern ball-bearing design, with the ball running along a groove in the axle assembly.

In this Design Squad Nation animation, Judy explains how the use of small steel balls can decrease friction and increase efficiency in a bearing, allowing a wheel to spin freely.

This edition of the series of programs explaining the technology used to produce items that are familiar in our daily life features ‘Steel Balls’. A bicycle wheel spins smoothly because the wheel axle contains ball bearings. The steel balls inside the ball bearing must be close to perfectly spherical. The program introduces the production method of high-precision steel balls with a margin of error of less than 0.1 micrometers.

Don't Forget To - LIKE | SUBSCRIBE | SHARE In this video i'm showing the main difference between standard steel ball bearings and full ceramic ball bearings which is the amount of friction that each has. You can immediately see the difference as soon as both are spun. I bought these in order to install them in my CNC steam turbine and see if it can actually produce more power for which i doubt that it will make a huge diffence, but we shall see;) Donate!: https://www.paypal.com/cgi-bin/webscr?cmd=_donations&business;=iliaioan%40hotmail%2ecom&lc;=US&item;_name=johnnyq90&no;_note=0¤cy;_code=USD&bn;=PP%2dDonationsBF%3abtn_donateCC_LG%2egif%3aNonHostedGuest Subscribe to my channel! https://www.youtube.com/user/johnnyq90 Follow me on Twitter! https://twitter.com/JohnnyQ90 Follow me on Goog...
