What can prolong the service life of the round head needle

Increasing the service life of cylindrical roller bearing has been a topic of great concern for a long time. Through long-term scientific research, it is found that the increase of service life of cylindrical roller bearing does not rely on only one countermeasure, but also needs to be maintained from various fields, including storage, cleaning, transportation, application, loading and unloading.

In order to increase the service life of the locating pin, it is not allowed to expose it in the gas. It must be stored in a clean, dry and temperature appropriate warehouse. It is also necessary to prevent it from being put together with corrosive chemicals such as acid, alkali and chemicals. In addition, in the whole process of transportation, it is also necessary to prevent deformation and damage caused by bumping and falling.

In addition to sealed bearings with covers on both sides, antirust agent is added to other locating pins when they are used in the original factory, as is the case for cylindrical roller bearings. Therefore, it is necessary to clean the equipment before application. The proper way is to infiltrate it into the vehicle gasoline stained with 8-10% mineral oil, wash off the antirust oil on the surface of rolling bearing, and the cleaned rolling bearing can not rotate again.

After the installation quality is the element endangering the service life of the cylindrical roller bearing, the shaft or hole of the supporting facilities shall be smooth and free of burr. If the reference point of the rolling bearing is correctly recognized under the condition that the requirements are met, it can be installed easily and timely. After the rolling bearing is installed, it should rotate easily without stagnation.

In addition, there is also an important step, that is to carry out appropriate lubrication for the length of the locating pin, select the appropriate intake system and high-quality lubricating fluid. Moreover, timely maintenance can prevent damage of cylindrical roller bearing caused by lubrication problem.

In order to increase the service life of cylindrical roller bearing, it is necessary to improve the characteristics of cylindrical roller bearing, so effective adjustment is very important. During assembly line or installation, if the internal clearance of rolling bearing is too large or too small, or in some cases, the preload is too high, it will cause initial damage and reduce the service life of rolling bearing.
