Bearing Installation and Use FAQ? First, the mounting surface and installation site requirements If the bearing iron, burrs, dust and other foreign matter from entering, will make bearings produce noise and vibration during operation, or even damage raceways and rolling elements. Therefore, before installing the bearing, you must make sure to clean the mounting surface and the installation environment. Second, must be cleaned before bearing installation bearing surface is coated with anti-rust oil, you must be carefully cleaned with gasoline or kerosene, and then coated with a clean high-quality or high-temperature grease before installation. Cleanliness influence on bearing life and vibration noise is very large. But we want to remind you is: totally enclosed bearings do not need to clean fuel. Third, the choice of lubricating grease has a very important impact on the operation and life of the bearing, here to brief you choose grease general principles. Grease the base oil, thickener and additives, grease performance of different types and different brands of the same type of linear bearings prices vary greatly, different rotation limit allowed, the choice is important to note. Grease performance is mainly determined by the base oil, generally low-viscosity base oil is suitable for low-temperature, high-speed linear bearings, high viscosity for high temperature, high load. Thickeners will also influence lubricating properties, water resistance determines grease thickeners water resistance. In principle, linear bearings business, you can not mix different brands of grease, and even the same kind of grease thickeners, also because of different additives adversely affect each other. LM linear bearings specifications and LME, LIN-11 and LIN-12, KH several series, including LM series for Asia, Southeast Asia, in metric dimensions as a standard, linear axis diameter tolerance is generally equipped with h7. LME series more for Europe, Germany, Italy and other regions, with inch dimensions as the standard, there are metric sizes, linear shaft diameter tolerance is generally equipped with g6. LIN-11 on behalf of the European standard plastic linear bearings, linear bearings installed using retainer limit supply, and LIN-12 series is a narrow design, the direct use of its outside diameter hole mount press fit, mainly in order to save installation space. Metal linear bearing is a low-cost production of linear motion systems, mainly for unlimited travel in conjunction with the cylinder axis. The plastic linear bearing is a self-lubricating properties of linear motion systems. The biggest difference between the two is that the metal linear bearing linear bearing is rolling friction, is the point contact between the bearing and the cylinder axis, so it is suitable for low-load high-speed movement; linear bearings and plastic sliding friction between the bearing surface contact with the cylinder axis It is suitable for high-load low-speed movement.
