Bearing Selection and Load Management Just like humans, bearings have to endure stress—and just like us, they perform best when they’re not overburdened. When selecting a bearing, ensuring its carrying capacity matches the demands placed on it is crucial. If the load exceeds the bearing’s capacity, the consequences can be severe. Accelerated fatigue or even permanent deformation might occur, drastically shortening the bearing's lifespan. Two types of stress are particularly important to consider: static and dynamic. Static stress doesn't imply a fixed load—it refers to the condition of the bearing itself. This happens when a load, whether steady or fluctuating, is applied to a stationary or very slow-moving bearing. Excessive force here can distort the rolling surfaces and flatten the rolling elements, effectively ending the bearing’s life prematurely and catastrophically. Dynamic stress, on the other hand, focuses on the bearing’s movement. It arises when a load, constant or variable, is applied to a bearing in motion. Overloading in this scenario leads to premature fatigue, causing cracks and flaking in weak areas. This results in failure due to material fatigue—a real-life “death” for your bearing. Three theories attempt to explain the causes of fatigue-related failures. Maximum shear stress theory suggests that the primary offender is the highest shear stress experienced by the bearing. Distortion theory posits that it’s the cumulative stress within a region, not a single point, that triggers fatigue. The alternating shear stress theory, however, argues that orthogonal stresses are the true culprits behind material fatigue. While each theory has its merits, alternating shear stress is widely used to calculate rolling bearing fatigue life. The fatigue life—or rating life—is defined as the number of revolutions or operating hours at a constant speed that 90% of identical bearings can endure before showing any signs of fatigue. Generally, as the load increases, the rating life of a group of bearings decreases. At Emerson Bearing, our expert technical team is ready to assist you in ensuring your bearings remain stress-free.
