The load capacity is the amount of load a bearing can handle and is one of the most important factors when choosing a bearing. Bearing loads can either be axial (thrust), radial or a combination. An axial (or thrust) bearing load is when force is parallel to the axis of the shaft. A radial bearing load is when force is perpendicular to the shaft.

Minimum load For additional information → Requisite minimum load: Use SKF Product select. If minimum load cannot be reached, consider preloading ( Selecting preload). Axial load carrying capacity: Pure axial load → F a ≤ 0.25 C 0 Excessive axial load can lead to a considerable reduction in bearing service life. Equivalent dynamic bearing load
