The importance of SKF spherical roller bearing sealing

Bearing seal is to make spherical roller bearings keep good lubrication condition and the normal work environment, give full play to the performance of the bearing, prolong service life, the rolling bearing must have appropriate sealing, in order to prevent the leakage of lubricants and the invasion of the dust, moisture or other contaminants. SKF bearing seal can be divided into two categories, own seal and seal. The so-called bearing with seal is made bearing itself into a sealing device. Such as bearing belt, etc. This seal take up the space is small, easy installation and disassembly, cost is low. Alleged bearing and sealing device, it is inside the installation end cover manufacturing into a sealing device has a variety of performance. Pair of roller bearing with seal selection should consider the following several major factors: the bearing lubricant and types ( And) ; The size of the bearing work environment, take up the space; Shaft supporting structure advantages, allowing the angular deviation; The circumference of the sealing surface speed; The working temperature of bearing; The manufacturing cost. Thickener is also related to oil, water grease thickener determines the resistance of the water. In principle, oil do not mix different brands, even if thickener, grease is also due to the different additives affect each other. Painted the bearing with anti-rust oil, must be clean petrol or kerosene cleaning carefully, and then use a clean, high quality or high speed high temperature grease before installation. Closed bearing not clean fuel. Self-aligning roller bearing in the installation, if not carefully adjusted, adjust bearing pain, may lead to more friction and vibration. These could accelerate fatigue, reduce SKF bearing mechanical parts may damage the life of a life. In addition, the increased vibration and friction can greatly increase the energy consumption and the risk of premature failure. In use process, often the basic monitoring of spherical roller bearing external, such as temperature, vibration and noise measurement conditions, and so on. Potential problem these regular examination, early detection, prevent the machine from accidental suspended, hence leading to the implementation of production plan, improve productivity and efficiency of the factory. In the process of operation, need the right bearing lubrication, to improve its performance. SKF bearing lubrication method, divide the grease lubrication and oil lubrication. In order to play a good function of spherical roller bearing, first of all, to choose the right condition, for the purpose of the lubrication method is used. If only considering the lubrication and oil lubrication dominant. However, can simplify the structure of bearing around the professional knowledge of grease.
