Bearings are mechanical elements that are indispensable to a wide number of applications, often serving to bear loads and facilitate the motion of moving parts while mitigating friction. Depending on the application and environment, various bearings may be used. In particular, roller ball bearing components, often referred to as rolling-element or rolling bearings, are those that take on loads through the use of rolling elements that are situated between races. Known for their optimal cost, size, weight, carrying capacity, friction, accuracy, and durability, it can be useful to have a general understanding of rolling-element bearings and their applications.
Rolling-element bearings are generally classified based on the type of rolling element that they feature, and the five primary types are those with balls, cylindrical rollers, spherical rollers, tapered rollers, and needle rollers. Ball bearings are often considered to be one of the most common variations, and they feature balls as the rolling element situated between races. The races are specifically designed to allow for a somewhat loose fit of the ball, making it so that each ball contacts the races across a narrow area.
Aside from ball bearings, there are numerous roller bearings that feature differently shaped rolling elements. The cylindrical roller is a common example, and they feature cylinders that have a length greater than their diameter. This design allows for an improved radial capacity when compared with the ball bearing, though this is at the cost of higher friction from axial loads. Cylindrical rollers also suffer from misalignment, that of which leads to a loss in bearing capacity. With their various characteristics, cylindrical bearings may be used for air conditioners, pumps, transmission systems, steering systems, and other such applications.
The spherical roller is another common option, featuring an outer ring that has an internal spherical shape. For rollers that are placed between races, the middle is typically thicker than the ends, allowing them to take on static and dynamic misalignment with ease. Despite this benefit, spherical rollers are often known for being somewhat expensive as a result of their more complex manufacturing process. Additionally, they exhibit higher friction when compared to cylindrical roller types as a result of sliding between rolling elements and races. For their use, spherical rollers are commonly implemented within gearboxes, windmills, automobiles, construction equipment, pumps, blowers, and other such assemblies.
For automobiles and other assemblies that require a greater contact area for carrying higher loads, the tapered roller is a good option. These hardware elements feature conical rollers placed on cone-shaped races, and they can take on radial and axial loads together. This makes them fairly beneficial for a number of assemblies, though they are often expensive due to their complex manufacturing process. Additionally, the force that maintains the roller in the bearing leads to increased friction when compared with standard ball bearing options.
Alongside such examples, other various rolling-element bearings exist, including those such as the needle roller and gear bearing.
