What are the characteristics of roller bearing?

Nowadays, bearings have become an essential objective in people's lives. The roller bearing is a typical kind of bearing that plays an important role in a different field. However, some people don’t know the importance of roller bearing.

This report will give a clear understanding of the characteristics of roller bearing, and make a rational analysis of the disadvantages of roller bearing.

What’s the basic structure of roller bearing?

Roller bearing has four major components, which are rolling parts, inner and outer rings, and support brackets. Rolling parts are the most important components, the shape of which can be changed as required. 

The roller bearing is with a short cylindrical, conical, or waist drum shape roller as the rolling body of rolling bearing. The main structural types are centripetal short cylindrical roller, double row centripetal spherical roller, tapered roller, and thrust roller.

It is noteworthy that, compared with ball bearings, the speed of roller bearings can be said to be relatively low. But relatively speaking, roller bearings have a large load-carrying capacity. The application of roller bearings not only improves the efficiency of mechanical transfer but also reduces mechanical damage and extends the service life of machinery.

What are the advantages of roller bearing?

The biggest advantage of roller bearings is that they are easy to dismantle, as the inner or outer ring can be separated, making them easy to mount and dismantle. It relies on rolling contact between the main elements to support the rotating parts.

As one of the main components in the light industry, the advantages of roller bearings do not require much introduction. It has a high degree of material purity, high wear resistance, and good dimensional stability.

In addition to this, roller bearings have high productivity. Its low coefficient of friction and high load-carrying capacity make them suitable for carrying heavy and shock loads.

The combination of a number of advantages makes roller bearings very popular among the majority of enterprises. Roller bearing size can be tailored to the customer's requirements, and different sizes correspond to different usage scenarios. Therefore, it is important to pay attention to the following before purchasing. Noticeably, many roller bearing manufactures are very strict with the original material they chose.

What are the disadvantages of roller bearing?

However, some issues need to be noticed. The most important one is the speed limit. Although roller bearings have the advantage of a higher load-carrying capacity, its ability to carry loads at high speeds has some relative limits.

Furthermore, the production of roller bearings is costly and time-consuming. In addition, roller bearings will make noise during operation. Noticeably, ball bearings also have the same disadvantage.

To summarize, a roller bearing is a multiple-functional material, it can be applied in many fields. Although it has some drawback need to be noticed, in terms of practicality, it is definitely one of the most valuable materials.
