What are the advantages of roller bearing?

Bearings are one of the most important materials in modern industry and it is hard to imagine how machinery would function nowadays without them. Roller bearings are a typical example of bearings that are favored by many customers for their excellent load-carrying capacity.

This report will give a clear overview of roller bearing, including its advantages and functions.

Why use roller bearing? 

There is no denying that roller bearing has a lot of benefits. The load-bearing capacity of roller bearings is the greatest advantage, which is a feature that ball bearings cannot have.

Apart from this, it has a high running accuracy, given that the strict international control of the accuracy of the roller bearings.

Roller bearings are extremely wear-resistant and work by reducing friction between machines, thereby increasing efficiency. In particular, roller bearings can accommodate changes in the position of the shaft in relation to the housing due to thermal expansion or mounting errors.

Where roller bearing can be applied?

The roller bearing is widely applied in many different fields, especially for the light industry. In spite of this, it can be used in many areas of machinery in the aerospace industry, electromechanical industry, manufacturing, agriculture, and many other areas.

It is known that medium and large 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 these equipment will use roller bearings.

Therefore, roller bearing can be defined to be a multiple-functional material, which plays a vital role in people’s lives.

What’s the basic structure of roller bearing?

There are four major components in roller bearing. Rolling parts, inner and outer rings, and support frames. Unlike ball bearings, the shape of the rolling elements of roller bearings can be varied according to requirements. In addition, the inner or outer rings of roller bearings can be separated easily, which is convenient for mounting and dismounting. This kind of design also increases working efficiency.

It is understood that the main structural categories can be divided into the following: Centred short-cylindrical rollers, Double rows of centripetal spherical rollers, Cone roller, and Structural types such as thrust rollers.

What are the types of roller bearing? 

The range of roller bearings cannot be defined by quantity, as stick bearings can be shaped to suit the customer's needs and different roller bearings are suitable for different use cases. A few common types of roller bearings are briefly listed here.

Tapered roller bearings, Cylindrical roller bearings, and Spherical roller bearings are the most common kinds of roller bearings on the market. Different roller bearings correspond to different structures, such as tapered roller bearing bearings, which consists of a taper, cup, tapered roller, cage four basic components of the structure has a relatively high radial load, axial load, and the ability to combine the load. Noticeably, Tapered roller bearing is generally used to support combined load mainly consisting of radial load.
