The performance of the grease is primarily determined by the base oil. Generally low viscosity base oils are suitable for low temperature and high speed; high viscosity is suitable for high temperature and high load. The thickener is also related to the lubricating properties, and the water resistance of the thickener determines the water resistance of the grease. In principle, different brands of grease cannot be mixed, and even greases of the same thickener can have a bad influence on each other due to the different additives. When lubricating INA bearings, the more grease is applied, the better. When lubricating miniature bearings, the more grease is applied, the better. This is a common misconception.
1, the installation of the bearing
Whether the bearing is installed correctly affects accuracy, life and performance. Therefore, the design and assembly department should fully study the installation of INA bearings. I hope to install according to the operating standards. The items of the job standard are usually as follows:
(1) Cleaning bearings and bearing related parts
(2) Check the size and finishing of the connected parts
(3) Installation
(4) Inspection after mounting the bearing
(5) Supply lubricant
2. Basic condition monitoring of bearings
During use, the basic external conditions of the INA bearing operation are often monitored, such as temperature, vibration and noise measurements. These regular inspections will identify potential problems early and will prevent unexpected machine stops, enabling production plans, increased plant productivity and efficiency.
3. Relubrication of the bearing
During operation, INA bearings require proper relubrication to perfect its performance. The method of micro-bearing lubrication 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.
4, the unloading of the bearing
When the bearing will reach its end of life, it should be replaced.
Although the INA bearing can no longer be used, correctly removing the original bearing and replacing the new bearing in time can promote the service life of the new bearing.
Excessive grease in the bearing and bearing chambers will cause excessive agitation of the grease, resulting in extremely high temperatures. How to install and remove Do not hammer the bearing end face and the non-stress face directly during installation. The micro bearing should be evenly stressed by the clamp, sleeve or other installation tools. If the mounting surface is coated with oil, it will make the installation smoother. If the interference is large, the bearing should be placed in mineral oil and heated to 90~100 °C and installed immediately. When disassembling is difficult, it is recommended that you use the disassembly tool to pull outward while carefully pouring hot oil onto the inner ring. The heat will cause the inner ring of the INA bearing to expand, making it easier to fall off.
