Difference Between Roller Bearings and Ball Bearings If you're looking to gain some basic understanding of roller and ball bearings, you've come to the right place. While we've definitely come across rolling and ball bearings, we may not be aware of the main difference between the two. Full Complement Cylindrical Roller Bearings When you look at them, on the surface, you may not find much difference. However, despite their similar appearance, they serve different purposes. In the next few lines, we will try to find out the main difference between the two. How Bearings Work The principles of bearings are the same. They have a ball placed in an outer or inner ring. When this happens, it can apply force to the ball. This is usually called loading. There are two types of loads, radial loads and thrust loads. When you choose radial load, it means the bearing will roll or rotate when in tension. On the other hand, when you use a thrust load, it is affected by a force, depending on the angle at which the thrust is applied. Bearings have been around for centuries and are used for rolling, pulling and other similar functions. Basic Difference Between Ball and Roller Bearings Ball bearings are used for smaller jobs such as spinning wheels and hard drives and other everyday applications. However, the problem with ball bearings is that they cannot withstand pressure and can deform or crack. However, when the load is light and manageable, both radial and thrust functions can be handled. This is the main reason why they are popular among engineers. The main job of a ball bearing is to transfer weight and make sure it moves from the outer race to the inner race. This ensures that the object rotates smoothly. On the other hand, when we talk about roller bearings, we are looking for something that can handle heavy loads. They are usually housed in cylinders. Therefore, they can better distribute the load over a larger area even if the load is heavy. This type of use distinguishes between ball bearings and rolling bearings. Both have their unique uses and properties, the most important being the end use.
