The sealing of the bearing is to maintain good lubrication conditions and normal working environment of the spherical roller bearing, give full play to the working performance of the bearing, and extend the service life. The rolling bearing must have a suitable seal to prevent the leakage of lubricant and dust, Intrusion of moisture or other dirt.

The seal of the bearing can be divided into two categories: self-sealing and external sealing. The so-called bearing comes with a seal is to make the bearing itself into a sealing device. Such as bearing belt, this kind of sealing space is very small, easy to install and remove, the cost is relatively low.

The so-called bearing plus sealing performance device is a sealing device with various properties manufactured inside the installation end cover. The selection of the external seal of the spherical roller bearing should consider the following main factors: bearing lubricant and type, bearing working environment, the size of the occupied space, the advantages of the shaft support structure, the allowable angle deviation, the circumferential speed of the sealing surface, The working temperature of the bearing and the manufacturing cost.

Spherical roller bearings are installed on, if not carefully adjusted, the adjustment may cause more bearing pain, friction and vibration. These may accelerate fatigue, reduce the life of mechanical parts such as bearings and may compromise service life. In addition, increased vibration and friction can greatly increase energy consumption and the risk of premature failure.

The thickener is also related to the lubricating oil, and the grease water thickener determines the water resistance. In principle, the grease does not mix different brands, even if the thickener grease, but also because of the different additives affect each other. Coat the bearing with anti-rust oil, clean gasoline or kerosene carefully, and then install it before coating with clean high-quality or high-speed high-temperature grease. Closed bearings do not require clean fuel.

In the use process, often spherical roller bearing operation of the basic monitoring of external, such as temperature, vibration and noise measurement conditions, these regular inspection, early detection of potential problems, to prevent the machine from unexpected suspension, so that the production plan can be achieved, improve the productivity and efficiency of the factory.

In the process of operation, the correct bearing re-lubrication is required to perfect its performance. Bearing lubrication method, the grease lubrication and oil lubrication points. In order to play a good spherical roller bearing function, to select the appropriate conditions, the purpose of the lubrication method used. If only lubrication is considered, oil lubrication is dominant. Can simplify the knowledge of the structure around the bearing grease.
