Importance of sealing performance of self-aligning roller bearing

The sealing of the bearing is to keep the self-aligning roller bearing in good lubrication conditions and normal working environment, give full play to the working performance of the bearing and prolong the service life. The rolling bearing must be properly sealed to prevent the leakage of lubricant and the invasion of dust, moisture or other dirt. The sealing of bearings can be divided into self sealing and external sealing. The so-called bearing with seal is to make the bearing itself into a device with sealing performance. Such as bearing belt, etc. The seal occupies little space, is convenient for installation and disassembly, and the cost is relatively low.
The so-called bearing external sealing performance device is to manufacture a sealing device with various properties inside the installation end cover.
For the selection of external seal of self-aligning roller bearing, the following main factors shall be considered:
Bearing lubricant and type (and); The working environment of the bearing and the size of the occupied space; The support structure of the shaft has the advantages of allowing angular deviation; Circumferential speed of sealing surface; Operating temperature of bearing; Manufacturing costs.
Thickener is also related to lubricating oil. Grease water thickener determines the resistance of water. In principle, grease is not mixed with different brands. Even thickener grease also affects each other due to different additives. To coat the bearing with antirust oil, it must be carefully cleaned with clean gasoline or kerosene, and then installed before coating with clean high-quality or high-speed high-temperature grease. Closed bearings do not require clean fuel.
Self aligning roller bearings are installed on the. If they are not carefully adjusted, the adjustment may lead to more bearing pain, friction and vibration. These may accelerate fatigue, reduce the life of mechanical components such as bearings, and may damage the service life. In addition, increased vibration and friction can greatly increase energy consumption and the risk of premature failure.
In the process of use, the basic monitoring of the operation of self-aligning roller bearings is often external, such as the measurement conditions of temperature, vibration and noise, and so on. These regular inspections can identify potential problems as early as possible and prevent accidental suspension of machines, so as to realize the production plan and improve the productivity and efficiency of the plant.
In the process of operation, correct bearing relubrication is required to improve its performance. The lubrication method of bearing is divided into grease lubrication and oil lubrication. In order to give full play to the function of self-aligning roller bearing, first, it is necessary to select appropriate conditions for the purpose of lubrication method. If only lubrication is considered, the lubrication of oil lubrication is dominant. However, expertise in the structure around the bearing can be simplified.
