Four Row Cylindrical Roller Bearing is a specialized bearing designed to accommodate high radial loads and provide high performance in heavy-duty applications.
As the name suggests, this type of bearing has four rows of cylindrical rollers, which are arranged in a unique way to achieve optimal load distribution and reduced friction. Four Row Cylindrical Roller Bearings are commonly used in steel mills, rolling mills, and other industrial applications that require high load-carrying capability and reliability.
These bearings are available in different sizes and designs, including different cage materials and precisions to suit specific application requirements. Overall, Four Row Cylindrical Roller Bearings are a reliable solution for large-scale, high-demand industrial applications.
The reasons for the failure of imported bearings are often multifactorial. All the influencing factors in the design and manufacturing process will be related to the failure of four row cylindrical roller bearings, which is difficult to judge by analysis. In general, it can be considered and analyzed from two aspects: use factors and internal factors.The Failure Causes of Four Row Cylindrical Roller Bearings in Use are Analyzed
Use factors mainly refer to whether the installation, adjustment, use and maintenance, maintenance and repair meet the technical requirements. The installation condition is one of the primary factors in the use factors. The improper installation of the four row cylindrical roller bearing often leads to the change of the stress state between the parts of the whole bearing, and the bearing operates in an abnormal state and fails early.
According to the technical requirements of bearing installation, use, maintenance and repair, monitor and inspect the load, speed, working temperature, vibration, noise and lubrication conditions borne by the running bearing, find out the cause immediately and adjust it to make it return to normal.
In addition, it is also important to analyze and test the quality of grease and the surrounding medium and atmosphere.The Failure Causes of Four Row Cylindrical Roller Bearings in Use are Analyzed

If you hear the noise from the inlet, first of all, it is important to find the location where the noise occurs. There are many moving parts that may produce noise, or some rotating parts may come into contact with non rotating parts. If it is confirmed that the noise in the four row cylindrical roller bearing may have been damaged and need to be replaced.
Since the working conditions leading to the failure of both sides of the front are similar, even if only one is broken, it is recommended to replace it in pairs.
Import is relatively sensitive, and correct methods and appropriate tools need to be adopted in any case. During storage, transportation and installation, the components of the bearing shall not be damaged. A large pressure is required to press in, so a special tool is required. Be sure to refer to the instructions.The Failure Causes of Four Row Cylindrical Roller Bearings in Use are Analyzed
It should be installed in a clean and tidy environment. The entry of small particles will also shorten the service life of four row cylindrical roller bearings. It is very important to keep a clean environment during replacement. It is not allowed to knock with a hammer. Be careful not to fall on the ground (or similar improper handling). Check the condition of the shaft and seat before installation. Even slight wear will lead to poor fit and damage.The Failure Causes of Four Row Cylindrical Roller Bearings in Use are Analyzed
The metallurgical quality of imported bearing materials was once the main factor affecting the early failure of rolling bearings. With the progress of Metallurgical Technology (such as vacuum degassing of bearing steel), the quality of raw materials has been improved.
The proportion of raw material quality factor in bearing failure analysis has decreased significantly, but it is still one of the main influencing factors of four row cylindrical roller bearing failure. Proper material selection is still a factor that must be considered in bearing failure analysis.The Failure Causes of Four Row Cylindrical Roller Bearings in Use are Analyzed
The main task of imported bearing failure analysis is to find out the main factors causing bearing failure according to a large number of background materials, analysis data and failure forms, so as to put forward targeted improvement measures, prolong the service life of four row cylindrical roller bearings and avoid sudden early failure of bearings.
