The importance of sealing spherical roller bearings

Bearing seal is in order to make the spherical roller bearings to maintain good lubrication conditions and normal working environment, give full play to the working performance of the bearings, prolong the service life of rolling bearings must have a suitable seal, in order to prevent the leakage of lubricant and dust, moisture or other dirt invasion.

Bearing sealing can be divided into two categories of self sealing and external sealing. The so-called bearing with sealing is the bearing itself manufactured into a sealing performance device. Such as bearing belt, this seal takes up very little space, easy to install and dismantle, the cost is relatively low.

The so-called bearing plus sealing performance device, is in the installation of end caps and other internal manufacturing into a variety of performance sealing device. Spherical roller bearings plus seal selection should consider the following main factors: bearing lubricant and type, bearing working environment, occupying the size of the space, the advantages of the shaft support structure, the permissible angular deviation, the sealing surface of the circumferential speed, bearing operating temperature, manufacturing costs.

Spherical roller bearings are mounted on, if not carefully carried out, the adjustment may lead to more pain, friction and vibration of the bearing. These may accelerate fatigue and reduce the life of mechanical components such as bearings possibly jeopardizing the service life. In addition, increased vibration and friction can greatly increase energy consumption and the risk of premature failure.

Thickeners are also related to lubricants, grease water thickeners determine the resistance of water. In principle, grease does not mix different brands, even if the thickener grease, the same due to different additives affect each other. Coat the bearings with antirust oil, clean them carefully with gasoline or kerosene, and then coat them with clean, high-quality or high-speed, high-temperature grease before mounting. Sealed bearings do not require clean fuel.

In the process of use, often self-aligning roller bearings running the basic monitoring of external, such as temperature, vibration and noise measurement conditions, these regular checks, early detection of potential problems, to prevent the machine from accidentally suspended, thus enabling the production plan to be realized, to improve the productivity and efficiency of the factory.

During operation, proper bearing relubrication is required to perfect its performance. The lubrication method of bearings will be grease lubrication and oil lubrication points. In order to play a good self-aligning roller bearings function, to choose the right conditions for the purpose of lubrication methods used. If only consider lubrication, oil lubrication lubrication dominates. You can simplify the knowledge of the structure around the bearing grease.
