Maintenance and inspection of NTN bearing several attention points - bearing knowledge
1, in the process of using the NTN bearing, regular cleaning is very first.
How accurate cleaning bearing?
Bearing will be removed when checking first, with the way such as photography first appearance record.
In addition, to confirm the amount of residual lubricant and lubricant sampling, and then clean the bearing.
2, bearing cleaning rough washing and fine washing suspension, can be put in use at the bottom of the container and on the metal frame.
3, rough washing, in oil partly brush eliminate grease or adhesive.
If at this time in oil migration change bearing, note due to foreign bodies such as blending mutilate rolling surface.
4, fine cleaning, slowly in the oil migration change bearing, must be hard to stop.
5, daily use of cleaning agent for neutral aqueous diesel or oil, according to the demand is also sometimes use warm lye, etc.
No matter use which kinds of detergent, often should clean filter confrontation.
6, after cleaning, immediately on the NTN bearing coating anticorrosive oil or antirust grease.
To import bearing longer do service for mechanical operation, regular of NTN bearing do regular testing is necessary, through the mechanical operation of the test can effectively find problems, to get good solve, effectively increase the service life of bearing.
The detection of main watch bearing have rivet head askew, relaxation welding position is correct.
The stand or fall of cage welding.
Weld is too small, welding is not strong, or welding caused by excessive card ball and so on.
Are in the process of testing imported bearing need special attention.
There are some problems need to be aware of.
About the detection of bearing is local.
First checks on imported bearing in the environment should be a light in the environment, had better be astigmatism, so as to better on bearing external, look at the surface and no crack, and other strange.
Such as mechanical cloud in the process of wear and scratches, touch, pressure will result in bearing assembly offset, leads to bad device position, cause flat load and stress concentration, the precision and reduce the service life of bearing modelling.
Work environment also pay special attention to moisture or contaminants, these are most likely to lead to bearing rust, rust is lead to adverse, NTN bearing installed early wear, would lead to more serious bearing scrap directly.
So in the process of using special attention to waterproof.
