What are the three types of loads that can be placed on bearings?

The three types of loads that can be placed on bearings are radial, thrust, and combination. This classification is essential for understanding how bearings interact with the machinery they support.

Radial loads are those that are applied perpendicular to the shaft, meaning that the weight or force is pushing downwards against the sides of the bearing. These loads are crucial in applications where the load is primarily vertical, like in rotating shafts where the weight of the attached elements creates such pressure.

Thrust loads, on the other hand, are forces that act parallel to the axis of the shaft. These are common in applications where the direction of the load changes, such as in axial fans or screw jacks. Understanding thrust loads is vital for ensuring bearings can handle forces that might try to push or pull the shaft along its length.

Combination loads refer to scenarios where both radial and thrust loads are acting simultaneously on the bearings. This situation often arises in real-world applications where the operating conditions are complex, necessitating bearings that can handle various forces at once.

The other options include types of loads that are either not specific to bearings or do not represent the primary categories of loads bearing designers must consider. Recognizing the distinction among these types of loads can greatly influence the performance, durability, and
