From the perspective of installation and maintenance of rolling bearings, there are many external factors that will affect the service life of the bearing, such as improper installation and improper maintenance. Wuxi Spark Bearing Co.,Ltd is here to share with you which of our common factors will affect the service life of bearings.
1. Analysis of installation factors
For example: the installation of the gland of the bearing seat of the conveyor roller and the sealing installation of the bearing seat are important factors affecting the performance of the bearing. The installation of the bearing housing gland directly affects the radial clearance of the bearing. Too small bearing clearance will cause the bearing to overheat, aggravate the wear of the bearing, and the wear resistance of the bearing will not be exerted. It may also directly cause the bearing to jam. So use the barley paper correctly before installing the gland .
Adjust the gland position.
The installation quality of the bearing seat seal (skeleton oil seal) affects the corrosion rate of the bearing. The roller bearing seat works in a watery environment. The damage of the seal during the installation process and the incorrect installation method will cause the bearing to enter the water with iron oxide impurities and accelerate the corrosion rate of the bearing components. When installing the skeleton oil seal, avoid mechanical damage, and the lip should face the outside of the bearing seat. WSBC 22314 CC/W33 bearings online , if you interested , pls click here :
2. Bearing maintenance factors
Such as: the maintenance of the conveyor roller table is divided into daily maintenance, operation inspection, and troubleshooting.The daily maintenance of bearings is mainly lubrication. In the case of sufficient lubrication, even in the most complicated working environment, the service life of the bearing can reach 5 to 10 years (about 200 million to 30 million revolutions), but under poor lubrication conditions The life of the bearing will drop to about 3 months (about 9 million revolutions).
The operation inspection of the bearing mainly detects the temperature of the bearing seat. The temperature of the bearing seat of the roller table before and after the rolling line is generally around 40℃. Even in the early stage of wear of the bearing cage and rolling elements, the temperature rise of the bearing seat is not high and will not exceed 43~45~C. However, with the further wear and inclusion of the internal components of the bearing, the temperature of the bearing seat will rise to 4550~C. At this time, the bearing of the rolling element changes .It is more uneven, even cracking and dislocation. Once the rolling elements are cracked or misaligned, the bearing seat will experience a sharp temperature rise. With the bearing seat smoking and the bearing stuck, the temperature measuring point of the bearing seat will rise to 150 to 170°C. At this time the bearing has been completely scrapped.
In order to achieve a longer service life of the bearing, in the early stage of bearing wear, the bearing should be cleaned and replaced in time, and the position of the bearing seat gland should be re-adjusted to increase or decrease the thickness of the gasket appropriately. In order to extend the life of the bearing.
3. Environmental factors
Although the operating environment of rolling bearings in the plate production line is complex, such as heavy load, high speed, and water, which affect the service life of rolling bearings, we can still make continuous efforts to improve the site to create a better environment for the bearings (such as: bearing seat The base is cushioned, the bearing seat is coated with a waterproof layer, etc.) to extend the life of the bearing.

Rolling bearing is a highly standardized precision mechanical component produced by a specialized factory. Among the many economic and technical indicators that affect rolling bearings, life indicators are the most direct, fastest and most comprehensive reflection of bearing quality. Although people have made accurate and complete considerations from design to overall structural design, sometimes due to uncertain negligence or some external
The factors that greatly reduce the service life of the bearing. Through a series of investigations, based on the analysis of a large number of background materials, analysis data, and failure modes, the main causes of bearing failure can be found, so that targeted improvement measures can be proposed to extend the service life of the bearing.
