Ball Bearing

A metal roller is a sort of moving component bearing that utilizations balls to keep up the partition between the bearing races. The reason for a metal roller is to lessen rotational grating and bolster outspread and hub loads. It accomplishes this by utilizing no less than three races to contain the balls and transmit the heaps through the balls. In many applications, one race is stationary and the other is connected to the turning get together. As one of the bearing races pivots it makes the balls turn also. Since the balls are moving they have a much lower contact than if two level surfaces were sliding against each other.
