ball bearings
A ball bearing is a variety of rolling-element bearing that uses balls to
take care of the separation between this bearing races.
The aim of a ball
bearing is to reduce rotational friction and support radial and axial loads. It
achieves this by employing at least two races to support the balls and transmit
the loads in the balls. In most functions, one race is stationary along with the
other is attached to your rotating assembly (e. g., a hub and shaft). As one of
many bearing races rotates the idea causes the balls to rotate as well. Because
the balls are rolling they also have a much lower coefficient involving friction
than if a couple flat surfaces were rotating on each other.
Ball bearings tend to own lower load capacity for a size than other kinds of rolling-element
bearings as a result of smaller contact area relating to the balls and races.
However, they can tolerate some misalignment with the inner and outer
contests.
