Extend the service life of INA miniature bearing common maintenance methods - bearing knowledge
INA 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 miniature bearing life and the influence of vibration noise is very big.
But we especially want to remind you is: fully enclosed bearing not clean fuel.
How to select grease lubrication of the bearing 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 the same kind of difference in different type of grease performance, 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, also on the basis of different addition agents bring bad influence to each other.
When INA bearing lubrication, grease lubrication coating, the better the more you miniature bearing, oil paint, the more the better, this is a common mistake.
1, the installation of the bearings bearing installation is correct, affects the precision, life and performance.
Therefore, design and installation of assembly department for INA bearing to fully research.
Hope to work in accordance with the standards for installation.
Operation standard project usually is as follows: (
Cleaning bearings and bearing components (associated
Check the size of the interrelated parts and finishing (
After installed bearing inspection (
Supply lubricant, bearing 2 basic condition monitoring during the period of using, often should basic external conditions of INA bearings running monitoring, such as temperature, vibration and noise measurement, etc.
These regular check will help identify potential problems and to prevent unexpected machine to suspend the phenomenon, make the production plan, improve plant productivity and efficiency.
3, bearing lubrication in the process of operation, again INA bearings requires correct lubrication again, perfect its performance.
Miniature bearing lubrication method, divided into grease lubrication and oil lubrication.
In order to make the bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method.
If only consider lubrication and oil lubrication.
But there are grease lubrication can simplify the structure of bearing around specialty.
4, bearing the unloading when bearing will reach its final use period, should be replaced.
Although INA bearings can not be used, but properly unloaded the original bearing, replace new bearing in time, to extend the service life of new bearing can play a good role in promoting.
Bearing and bearing indoor excessive grease will cause excessive oil mixing, resulting in a high temperature.
How to install and remove the installation not hammer bearing end face and the bearing surface directly, should with press, sleeve or other installation tools for uniform miniature bearing force.
If the installation surface coated with lubricating oil, will make the installation more smoothly.
If the interference fit is larger, should put the bearing into the mineral oil heating to 90 ~ 100 ℃ in immediately after installation.
When removing difficulties, it is recommended that you use disassembly tool to pull at the same time to careful labor the inner ring of hot oil, heat can make the INA bearing inner ring expansion, from but make it easier to fall off.
