6208 Deep Groove Ball Bearing 40x80x18mm Chrome Steel IP5 Sealed

Ball bearings are used to reduce friction during rotation and support various loads. It does this by using two or more tracks to accommodate the balls and transfer the weight of the load through the balls. Typically, one track sits in the hole and remains stationary while the other track is fixed in the rotating part. The system works simply because if the shaft is set on a rolling unit as opposed to freely rotating, there is less friction, allowing the surfaces to slide against each other.

When the ball bearing rotates with the load, because the raceway surface of the ring and the rolling surface of the rolling element are continuously subjected to alternating loads, even if the use conditions are normal, the raceway surface and rolling surface will appear fish scale damage due to material fatigue. Called exfoliation or exfoliation. The total number of revolutions before this rolling fatigue operation occurs is called the "(fatigue) life" of the bearing.

Even for bearings with exactly the same structure, size, material, processing method, etc., when rotating under the same conditions, the (fatigue) life of the bearings will still have a large difference. This is because material fatigue itself is discrete and should be considered from a statistical point of view.
