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.

long-life low-noise high-temperature bearing grease
In the environment of high temperature and high grease used should have the following characteristics:
(1) no loss at high temperatures, i.e. at a temperature of about 180 ℃ maintain a certain consistency, is not softened.
(2) oil leak less. When the grease in the Backing bearings to withstand repeated high shear and large centrifugal force, the lubricant can not promptly thrown back into the raceway.
(3) has a certain muted effect, a high temperature grease tapered bearing fibers are generally large, so in the bearing noise test is far less than the acoustic performance of lithium-based grease.
(4) have a certain kind of high-temperature grease life at high temperatures with good oxidation resistance, thus extending the life of bearings and related equipment.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 bearing 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.
