Bearing the seal is self-aligning roller bearings to maintain good lubrication conditions and normal working environment, give full play to the performance of the bearing, extend the service life of rolling bearings must have the appropriate seal to prevent lubricant leakage and dust, the intrusion of moisture or other contaminants. SKF bearing the seal can be divided into own seal and external sealing two categories. The so-called bearing comes with sealed bearing itself is manufactured with sealing performance of the device. Such as bearings with, and so on. This sealed space is small, easy installation and removal, the cost is relatively low.
The so-called external bearing sealing performance devices, is to install the end cap and internal manufacturing performance seals.
Swap roller bearings plus sealed the choice should consider several factors:
Bearing lubricants and types (and); bearing the working environment, the size of the space; the shaft supporting structure advantages, allows the angle of deviation; sealing surface of the circumferential velocity; bearing operating temperature; manufacturing costs.
Thickener is also related to the lubricating oil, grease water thickener to determine the resistance of the water. In principle, the grease does not mix different brands, even if the thickener grease is also due to the different additives affect the other. Bearings, anti-rust oil coating must be clean gasoline or kerosene is carefully cleaned, and then use a clean, high quality or high temperature grease coating before installation. Closed bearings do not need to clean fuels.
Spherical roller bearings installed in the last, if not carefully adjusted, the adjustments may result in bearing pain, friction and vibration. These may accelerate fatigue, and reduce the life of SKF bearings and other mechanical components may impair the period of use. In addition, an increase of the vibration and friction can greatly increase energy consumption and the risk of premature failure.
During use, they often tune the basic monitoring of roller bearings running external measurement conditions such as temperature, vibration and noise, and so on. These regular check-ups and early detection of potential problems and prevent machine accidents pause, so that the production plan to be realized, and to increase plant productivity and efficiency.
During operation, you need the correct bearing re-lubrication, and improve its performance. SKF bearings lubrication, grease and oil lubrication points. To play aligning roller bearings feature to select the right conditions, the purpose of lubrication method. If you only consider the lubrication oil lubrication lubrication dominated. However, you can simplify the expertise of grease around the bearing structure.
