KOYO bearing lubricating oil of the normal use of color is brown and dark blue.
If a part, it shows that the oil blended with diesel or moisture, should be replaced in a timely manner.
If dark black, it showed that the oil has been bad, must be timely replacement.
The thesis& oil drops after stir in white paper (
It's best to filter paper)
, form the oil stain, staining outward from the center after about 2 ~ 3 hours of gradually spread, form three concentric rings.
According to the color of the three regions, size and shape can identify the state of the oil.
From the lower shell oil with a little oil, besmear is on the fingers, fingers and thumb twist mill.
If you have any impurity or feel oil like water without a sticky feeling, even send acerbity or have a sour taste, oil has been bad.
If twist after grinding on the finger to see small shiny metal grinding, the serious wear and tear parts, engine are also shows that the oil must be replaced immediately.
1, judging from KOYO bearing dimensions need to first focus on KOYO bearing internal clearance dimension precision, rotating accuracy, as well as the matching surface, raceway surface, cage and sealing ring, etc.
Then for the test results can be used to bearing the judgement or master of bearing.
2, KOYO bearing whether or not to use the standard of judgment of whether to use the standard to KOYO bearing according to their mechanical properties and important degree and the concrete analysis of check cycle, etc.
If appear fracture and defect and the surface of the raceway of bearing parts content on the surface of the rolling strip two phenomena, the bearings shall not be used again, have to be replaced.
Using KOYO import bearing in the process, in order to be able to make it can give full play to and maintain its performance for a long time, the preventive maintenance measures should be done well.
Can through the following practical questions of appropriate cleaning order measures, improve the efficiency of the use of the bearing.
3, KOYO bearings cleaning method first KOYO bearings will be removed in check, and make records.
In addition, to confirm the amount of residual lubricant and lubricant sampling, and then clean the bearing.
In general, KOYO import bearing the detergents for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc.
No matter use which kinds of detergent, often should filter clean.
After good NTN bearing cleaning, need immediate coating anticorrosive oil or antirust grease.
