Bearing Lubrication method
The lubrication method of the bearing is divided into grease lubrication and oil lubrication. In order to make the bearing function well, first, choose a lubrication method that suits the conditions of use and the purpose of use. Lubricity of oil lubrication predominates if only lubrication is considered. However, grease lubrication has the advantage of simplifying the structure around the bearing, comparing the advantages and disadvantages of grease lubrication and oil lubrication. Pay special attention to the amount of lubrication, whether it is oil lubrication or grease lubrication, too little lubrication does not fully affect the bearing life, too much will produce a large resistance, affecting the speed.
Bearing seals can be divided into self-contained seals and external seals. The so-called bearing self-contained seal is to manufacture the bearing itself into a device with sealing performance. Such as bearings with dust cover, sealing ring and so on. The seal has a small footprint, is easy to install and disassemble, and has a relatively low cost. The so-called bearing external sealing performance device is a sealing device having various properties manufactured inside a mounting end cap or the like. Bearings and seals are divided into non-contact seals and contact seals. Among them, the non-contact seal is suitable for high speed and high temperature applications, and has different structural forms such as gap type, labyrinth and washer type. Contact seals are suitable for medium and low speed working conditions, and are commonly used in the form of felt seals and cup seals.
