Ina bearing surface is coated with antirust oil. You must carefully clean it with clean gasoline or kerosene, and then apply clean high-quality or high-speed and high-temperature lubricating grease before installation and use.
Cleanliness has a great influence on the service life and vibration noise of micro bearings. However, we Ina Micro Bearing would like to remind you that there is no need to clean and refuel the fully enclosed bearing.
How to choose grease lubrication has a very important impact on the operation and service life of bearings. Here is a brief introduction to the general Ina Micro Bearing principles of selecting grease. Lubricating grease is made of base oil, thickener and additives.
The performance of different kinds and different brands of lubricating grease of the same kind varies greatly, and the allowable rotation limit is different. Be sure to pay Ina Micro Bearing attention to it when selecting.
The performance of grease is mainly determined by base oil. Generally, base oil with low viscosity is suitable for low temperature and high speed; High viscosity is suitable for high temperature and high load.
The water resistance of thickener determines the water resistance of grease. In principle, greases of different brands cannot be mixed, and even greases with the same Ina Micro Bearing thickener will have bad effects on each other due to different additives.
When lubricating ina bearings, the more grease, the better? When Ina Micro Bearing lubricating micro bearings, the more grease, the better. This is a common misconception.
Whether the bearing is installed correctly affects the accuracy, service life and performance. Therefore, the design and assembly department should fully study the installation of INA Bearing. It is hoped that the installation will be carried out according to the operating standards. Items of operating standards are usually as follows:
(1) Clean the bearing and its related parts
(2) Check the size and finish machining of related parts
(4) Inspection after bearing installation
(5) Supply lubricant
2. Basic condition monitoring of bearing
During use, the basic external Ina Micro Bearing conditions of INA Bearing operation should be monitored frequently, such as temperature, vibration and noise measurement.
These regular inspections will identify potential problems as soon as possible, prevent unexpected machine stoppage, realize the production plan and improve the productivity and efficiency of the plant.
3. Re lubrication of bearings
In the process of operation, INA Bearing requires correct re lubrication to perfect its Ina Micro Bearing performance. The lubrication methods of micro bearings are divided into grease lubrication and oil lubrication.
In order to make the bearing function well, first of all, choose the lubrication method suitable for the use conditions and purposes. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the structure around the bearing.
4. Unloading of bearing
When the bearing will reach its final service life, it should be replaced.
Although ina bearings can no longer be used, correctly removing the Ina Micro Bearing original bearings and replacing new bearings in time can play a good role in prolonging the service life of new bearings.
Excessive grease in the bearing and bearing chamber will cause excessive mixing of grease, resulting in extremely high temperature. How to install and disassemble? During installation, do not directly hammer the bearing end face and non stress surface. Use pressure block,
sleeve or other installation tools to make the micro bearing bear uniform stress. If the mounting surface is coated with lubricating oil, the installation will be more smooth. If the fit interference is large, put the bearing into mineral oil and heat it to 90 ~ 100 ℃ before installation.
In case of difficulty in disassembly, it is recommended that you use the disassembly tool to pull outward and carefully pour hot oil on the inner ring. The heat will expand the inner ring of INA Bearing and make it easier to fall off.
