The development of bearings has been underway for thousands of years. With the development of time, there are a growing number of different types of bearings, which correspond to different use scenarios. For the modern light industry, bearings can be said to be the most important material. The appearance of bearings can help machinery to improve efficiency and reduce wear and tear, bearings can be said to be the product of technology.
Currently, we will focus on the history of the development of roller bearings.
Who invented roller bearing?
Where can roller bearing be applied?
Why use roller bearing?
What are precautions when using roller bearing?
When talking about the development history, it’s worth pointing out such as a person, John Harrison. He invented the first practical caged-roller bearing in the mid-1740s. This kind of bearing uses bearings with a very limited oscillating motion, which paved the way for the later development of bearings.
There are several common designs of roller bearings, each with different performance trade-offs. Meanwhile, there are five types of rolling elements that are applied in rolling-element bearings: balls, cylindrical rollers, spherical rollers, tapered rollers, and needle rollers.
There is no denying that roller bearing can be widely used in many sectors. The light industry is the most important sector.
To be more precise, large and medium-sized electric motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, reduction gearboxes, rolling mills, vibrating screens, and lifting and transport machinery all make use of roller bearings.
Nowadays, roller bearing has become a common thing in people’s lives. The working principle of roller bearings is simple, to reduce friction by rolling. At the same time, roller bearings have a number of advantages, the most notable of which is that they are designed to withstand heavy and shock loads due to their ability to withstand gravity.
Besides, roller bearings can be used with suitable tolerances, it can accommodate changes in the position of the shaft in relation to the housing due to thermal expansion or mounting errors. What’s more, it can be used as free-end bearings, it’s a very flexible material. Furthermore, it can be freely removed and dismantled.
In addition, roller bearings have a narrow friction coefficient, which is due to the fact that each roller bearing manufacturer has a fixed production pattern, which is very stable and does not vary with the coefficient of friction during normal operating conditions.
Although roller bearing a kind of multiple-functional material, it also has some drawback need to be noted. The production efficiency of roller bearings is slow. As a result, the bearings are relatively expensive. On top of this, although roller bearings have a higher load-carrying capacity, they have a speed limit, which will have an influence on their use in the future.
Finally, the choice of materials varies from one roller bearing manufacturer to another. So We recommend choosing a larger manufacturer and customizing the dimensions to suit your needs.
