[0002] The sliding rail device is widely used in mechanical equipment, transmission system or furniture to facilitate relative sliding between the first element and the second element.

[0003] In the existing sliding rail device, a guide rail and a sliding block are usually included, and the guide rail is slidingly installed on the sliding block. In order to reduce the friction of the sliding block on the guide rail, a plurality of spherical balls are usually arranged in the sliding block, and the spherical balls are in rolling friction with the sliding block during the sliding of the sliding block. Although the sliding device with the spherical balls can reduce the friction of the sliding rail device, the wear of the spherical balls is uneven, and the worn spherical balls are likely to be no longer standard spherical. The rolling direction of the spherical balls that are not standard spherical is selective, for example, when the spherical ball becomes an ellipsoid, the direction in which it is easy to roll is around its long axis. At this time, if the ellipsoidal ball is in the sliding groove and its long axis is consistent with the sliding direction of the sliding block, the ball is not easy to roll and shows sliding, which will increase the friction of the sliding block and thus affect the service life of the sliding rail device.
