| A bearing is
a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.The purpose of a 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, roller and transmit
the loads through the balls or roller. 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. you can
earn any kind of bearing that you want by just visit the ZAPAAS site. |
