The number of revolutions of one ring or rolling element of a bearing before fatigue pitting occurs for the first time is the number of revolutions of one ring relative to the other ring, which is called the life of the bearing. The length of the bearing life will affect bearing sales’ rate.

Bearing sliding restriction is one of the important factors affecting bearing performance. Various rolling bearings themselves have different degrees of sliding factors. Misalignment of installation, too loose or tight fitting, improper selection of clearance, etc. will all make the sliding factor in the bearing become a significant cause.

Low bearing cleanliness is also an important factor affecting bearing performance. If the bearing manufacturer guarantees the cleanliness of the bearing products, the workers guarantee the cleanliness of the bearings in the process of cleaning, installation and lubrication, and the lubricant supplier guarantees the cleanliness of the lubricant itself. If any link is negligent, It may cause the bearing to be contaminated.

The maintenance work of the conveying roller table is divided into daily maintenance, and the daily maintenance of the transport bearing is mainly lubrication. Under the condition of sufficient lubrication, even in the most complex working environment, the service life of the bearing can reach 5 to 10 years (about 200 million ~300 million revolutions), but the life of the bearing will be reduced to about 3 months (about 9 million revolutions) under poor lubrication. Therefore, bearing maintenance factors are also important factors affecting bearing performance.

The operation inspection of the bearing mainly detects the temperature of the bearing seat. The temperature of the roller bearing seat before and after the rolling line is generally around 40°C. 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 45-50°C. At this time, the bearing of the rolling elements becomes more uneven, and even cracks and dislocations occur. Once the rolling elements are cracked or misaligned, the bearing housing will experience a sharp temperature rise. With the bearing housing smoking and bearing jamming, the temperature measuring point of the bearing housing 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 housing gland should be re-adjusted to increase or decrease the thickness of the gasket appropriately to extend the service life of the bearing. The service life of the bearing is prolonged, and the corresponding bearing sales rate will also increase.

Although the operating environment of rolling bearings in the plate production line is complex, such as heavy load, high speed, and excessive 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 service life of the bearing. Environmental factors are one of the important factors affecting bearing performance. To increase bearings sales’ rate, a little effort is needed in terms of life.
