IKO bearing the preparation before installation and removal

IKO bearing installation should be carried out in a dry, dust-free interior, and stay away from metal processing or other equipment will produce metal pieces and speechless and dust. When must be installed in the unprotected environment bearing ( Larger bearings are often encounter this kind of circumstance) , must take the appropriate measures to protect bearings and related parts from pollution of dust or moisture and so on, until the installation is complete, such as using packaging stencil or foil paper will bearings and related parts covered or wrapped. The preparation before installation and removal before installation, should be ready all the necessary spare parts, tools, equipment and related data, and so on. Carefully study the drawings and related instructions, to determine the correct installation order of different parts. Careful examination, shaft, bearing, seal and other parts of bearing configuration, to determine mating surface clean and good, should also be a special check the screw hole, catheters or groove, in order to prevent some processing residues. The casting of bearing seat, shall ensure that no core sand on the surface of the some without machining, and remove all the burrs. Check the bearing of all components in the configuration of dimensional tolerance and shape tolerance of related parts must meet the required precision and conform to the provisions of the tolerance range, the performance of the bearing can exert. The diameter of the cylindrical shaft and hole, general with micrometer or inside diameter micrometer in two cross section and four different position measurement. Journal of the taper ring gauge available measure, special taper gauge or sine bar. Measurement results and related inspection, it is suggested that keep records, in order to offer the reference needs into. When measuring, components and measuring instrument should be kept in roughly the same temperature, so as to ensure the accuracy of measurement. That may need to components and measuring equipment in the same place quite a time, in order to achieve the same temperature. This is especially important for large bearings and related components. Bearing should be retained in the original packaging until the moment before the installation, in order to prevent the dust pollution, such as to enter. In the general case, no need to remove before delivery) on the bearing of the rust inhibitor, simply wipe IKO bearing outer circle and inner hole. But if the bearing with grease lubrication and application in high or low temperature or the grease is not compatible with the rust inhibitor, is necessary before installing the bearing and carefully dry cleaning, in order to avoid damage to the role of the grease. If the bearing due to improper handling, Packing damage, for instance) And are likely to be pollutants into, will also be necessary to the bearing cleaning and dry before installation. From the original packaging bearing, if relatively thick rust inhibitor on the surface or have higher viscosity, is also need to put the bearing cleaning and dry. Part of bearing outside diameter greater than 420 mm oversize may have this kind of situation, this situation can use solvents or paraffin oil to clear the rust on the bearings. If you are using IKO bearings with seals or dust cover, due to the factory to fill grease, not clean before installation. 1, the installed on surface and the place has a requirement? If IKO bearing with iron filings, burr, dust and other foreign matter to enter, will make the bearing noise and vibration during operation, even damage raceway and rolling body. So, before the installation of bearings, you must ensure that the installation surface and the environment clean. 2, IKO bearings must be cleaned before installed? IKO bearing surface coated with anti-rust oil, you must use clean petrol or kerosene cleaning carefully, then coated with clean, high quality or high speed high temperature lubricating grease before installation. Cleanliness of IKO bearing life and the influence of vibration noise is very big. But we especially want to remind you is: fully enclosed IKO bearing not clean fuel. 3, how to select grease? Lubrication of IKO import bearing of work and life have very important influence. Here a brief introduction to select the general principles of the grease to you. Grease made out of base oil, thickener and additive, different types and different type of same kind grease properties vary widely, allowing the rotation of the limit, when the choice is important to note. The performance of the grease is mainly determined by the base oil. The basis of generally low viscosity oil is suitable for low temperature, high speed; High viscosity is suitable for high temperature, high load. Thickener and relationship with lubrication performance, thickening agent, water resistance to the water resistance of the grease. In principle, different brand of grease can't mix, and even the same thickening agent of grease, will also bring bad influence each other on the basis of different additives.
