For SKF bearings into full play and to maintain its long-term performance, would like to propose the following several tips.
Through appropriate checks on a regular basis, so that early detection of failures, prevent accidents in the future, to increase productivity and economic importance.
1, cleaning
Remove the bearing inspection, using methods such as photographic appearance record. In addition, sampling to confirm the amount of remaining lubricants and lubricants and cleaning FAG bearings.
A, bearing wash wash the cleaning of rough and refined, and can use the metal rack on the bottom of the container.
When b, heavy wash, clear, such as in oil with a brush grease or adhesive material. When rotating bearings in oil, attention due to foreign body injuries, such as scrolling.
C/finish when washing, slowly rotating bearings in oil, be careful.
Cleaning agent which is commonly used as neutral does not contain water, diesel fuel or kerosene, Lye, sometimes using temperature as needed. Regardless of what kind of cleaning agents, are often filtered clean.
After washing, immediately on NSK bearing coating rust preventive oil or antirust grease.
2, check with the judge
To determine the bearing can be removed again, to focus on checking its accuracy, rotating accuracy, internal clearance, and the mating surfaces, roller cage and seals.
On the inspection results, may be used to bearing or bearing savvy to judge.
Criteria based on the mechanical properties and importance vary depending on the level and check the cycle. If there is damage, bearing shall not be reused and must be replaced.
1) faults and defects of bearing components.
2) split of Raceway surface scroll surface.
Bearing fault identification method
Not by removing checks to identify or forecast TIMKEN bearing in a trouble-free operation, to improve productivity and economy are very important.
Major recognition methods are as follows:
1) by voice recognition
Voice recognition requires a wealth of experience. Must be fully trained voices able to identify bearing and non-bearing sound. This should be done by hand as far as possible to make this work. Listen to audio or sound bar attached to the shell can be clearly heard INA bearing sound.
2) through to identify operating temperature
The method is a method to identify, is limited to use in running conditions don't change. To this end, the need for continuous recording of the temperature. Fails, not only temperature, irregular changes also occur.
3) through State recognition of lubricants
Sampling analysis of lubricants, mixed with foreign objects through the degree of dirt or metal powder for judgment. The method near the observation or large bearings are particularly effective.
