Under the action of a certain load, the bearing in the event of pitting before the number of revolutions or hours, known as bearing life.
The life of a rolling bearing is defined in terms of the number of revolutions (or hours worked at a certain speed): A bearing within this life-cycle shall be subject to preliminary fatigue damage (peeling or defect) on any of its bearing rings or rolling elements. However, whether in laboratory tests or in actual use, can be clearly seen in the same working conditions, the appearance of the same bearing, the actual life is very different.
In addition there are several different definitions of bearing "life", one of which is the so-called "working life", it means that a bearing before the damage can be achieved by the actual life is wear and tear, damage is usually not caused by fatigue, but From wear, corrosion, sealing damage and other reasons.
We all know that idlers are the heart of belt conveyors. The good sealing performance of the roller bearing requires strict quality control of the component parts to ensure the local structural and sealing properties, so that the roller bearing seat has a good sealing performance. While extending the gap and length of the maze to improve the sealing effect, can extend the roller life. Roller bearing housings are widely used in open dusty and corrosive environments, such as mines, power plants, steel mills, stone plants, cement plants and coking plants, coal preparation plants, saltworks, soda plants, fertilizer plants, All transport sites. According to the size of different enterprises, the needs and the use of different number of rollers, according to their own actual situation to meet the production and processing needs. As most of the belt machine work environment, dust pollution is serious, and corrosive, in particular, some hard particles on the roller tube body wear and tear unusual. Although a lot of manpower and material resources are often used to repair the roller, however, the use of roller bearing large, frequent early failure, resulting in harsh sounds until the card is completely damaged, people can not keep up, failure downtime Which restricts the normal operation of belt conveyor production line. And a substantial increase in labor intensity, regular work in high dust environment in the human health also caused serious harm. For a long time, the traditional roller in the harsh environment of the life of only a few hundred hours. Early roller failure, resulting in frequent conveyor failure, tear tape, and even casualties occur accidents are not uncommon.
