ball bearingis a type ofrolling-element bearingthat usesballsto maintain the separation between thebearingraces.
The purpose of a ball bearing is to reduce rotational friction and supportradialandaxialloads. 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., ahubor 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 lowercoefficient of frictionthan if two flat surfaces were sliding against each other.
Ball bearings tend to have lowerload capacityfor 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.
