Sliding Doors 61.5*90*12mm Iron Ball Bearings
Description:
Deep Groove 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 three 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.

Deep Groove Ball Bearing Classification:
According to the size of deep groove ball bearings, they can be divided into:
(1) miniature bearings -- bearings whose nominal diameter is less than 26mm;
(2) small bearings -- bearings with nominal outer diameter of 28-55mm;
(3) small and medium-sized bearings -- bearings with nominal outer diameter of 60-115mm;
(4) medium and large bearings -- bearings with nominal outer diameter of 120-190mm.
(5) large bearings -- bearings with nominal outer diameter of 200-430mm;
(6) extra large bearings -- bearings with a nominal outer diameter of 440mm or more
