Backing bearings are particularly thick outer ring of the rolling bearing, when used to form a group to be mounted on the shaft of a stationary support rollers. Pressure on the work roll through the intermediate roller and the support roller is passed to the system to the rack through the saddle. Generally used for multi-roll cold rolling mill equipment can also be used for other occasions, such as straightening machine.

HRB main bearing damage analysis
Dealt with in the short term if the cause, and take appropriate action, bearing damage to the mechanical parts than the average damage is much more complex, tapered bearing damage is characterized by a manifestation of many complex causes, bearing damage in addition to bearing design and manufacture intrinsic factors, mostly due to improper use.
In the course of external conditions because of their quality and the reasons for its carrying capacity, rotation accuracy and friction energy performance will change, when the backing bearings performance is lower than the requirement was not working properly, it is called bearing damage or failure, bearing in the event of unforeseen circumstances such damage will occur when its machinery, equipment stops, functional damage, and other anomalies.
Research bearing damage and causes the formation of two specific areas:
1, use can be improved, the correct use of the bearing, should give full play to the performance of the bearing,
2, contribute to the development of new products with better performance.
