When judging whether the disassembled Thin-walled bearing can be reused, check it after IKO bearing cleaning, and carefully check the state of raceway surface, rolling surface and mating surface, the wear of cage, whether the bearing clearance increases, and whether there are damages and abnormalities that affect the decline of dimensional accuracy.
For non separable small ball bearings, use one hand flat end inner ring and rotate the outer ring to confirm whether it is smooth.Simple treatment of problems affecting the service life of IKO thin wall bearing

Simple treatment of problems affecting the service life of IKO thin wall bearing For separate bearings such as bearings, the raceway surfaces of rolling elements and outer rings can be inspected respectively.
Since large bearings cannot be rotated by hand, pay attention to the appearance of rolling elements, raceway surfaces, cages, edge retaining surfaces, etc. the higher the importance of bearings, the more careful the inspection is.
When judging whether the bearing can be reused, it should be determined according to the damage degree, mechanical performance, importance, operating conditions, inspection cycle and other relevant factors of the Thin-walled bearing.
However, if the following defects are found during the inspection, the bearing can not be used anymore and needs to be replaced with a new IKO bearing.Simple treatment of problems affecting the service life of IKO thin wall bearing
1. Under lubrication condition, the viscosity forms a lubricating film between the rolling contact surfaces enough to separate the two surfaces. The lubricant must maintain a certain low viscosity at normal working temperature to reduce bearing friction and improve bearing life.
The main factors affecting the noise are the average diameter of the bearing and working speed Working viscosity the viscosity of lubricant at the working temperature is determined by the nominal viscosity at the working temperature T4 ℃ according to the viscosity temperature curve, and the viscosity ratio is an index indicating the ability of oil film formation.Simple treatment of problems affecting the service life of IKO thin wall bearing
Its rotating speed and other factors have a great impact on the service life of the bearing. When the operating state becomes worse (temperature increases, rotating speed decreases, and pollutants increase), the service life of IKO bearing may be greatly polluted and greatly reduced.Simple treatment of problems affecting the service life of IKO thin wall bearing
2. Calculation of bearing life correction coefficient and analysis of influencing factors calculation method of correction coefficient Analyze various factors affecting the correction coefficient, calculate a basic coefficient of bearing life, and make the Thin-walled bearing get better lubrication conditions.
It should be greater than or equal to, but the viscosity ratio should not be too large, otherwise the increase of viscosity may increase the working temperature of the bearing When the lubricating oil containing extreme pressure additives should be used, in addition, the pressure between moving surfaces will also change the viscosity of the lubricating oil.Simple treatment of problems affecting the service life of IKO thin wall bearing

The symbolic meaning calculation methods consider the influence of operating conditions (operating temperature, speed load transfer and lubrication conditions on the service life of IKO bearing.Simple treatment of problems affecting the service life of IKO thin wall bearing
Bearings are built and reformed with insulating covers, usually with paper or other container covers at one time, transported with a wooden frame and bamboo paper or gradually sent at one time. If there is a plastic sheet roller and tapered roller bearing cup.Simple treatment of problems affecting the service life of IKO thin wall bearing
Bearing lubrication to ensure good effect. Check whether the lubricating oil pump is in good condition and the pipeline flow spark specification oil tank to ensure sufficient oil supply. The lubricating oil is clean and free of dirt.
At the same time, it is within the range of the cursor for an appropriate time and according to the correct gear oil. After checking the oil viscosity in winter for about five minutes, you can run the oil slowly, indicating that it is necessary to take compensation level.Simple treatment of problems affecting the service life of IKO thin wall bearing
The bearings shall be used in a standardized manner until the end of the service life of IKO bearings. Such cases are relatively rare. Generally, the bearings are damaged due to various reasons in the process of operation and production, and the bearings are directly scrapped if they are serious.
These reasons are nothing more than installation, use and lubrication. The common causes are the clamping injury of the ferrule edge of thin-walled bearings, and the main reason is insufficient lubrication or foreign matters.

In view of these problems, we should first eliminate the causes of the accident, and investigate the recurrence of similar accidents on one side in combination with the use environment, location, structure and other aspects, which will bring unnecessary trouble.Simple treatment of problems affecting the service life of IKO thin wall bearing
