In order to ensure that the bearing has been good running, periodic maintenance maintenance is necessary, so as to achieve protection against accidents and proactively, and improving production efficiencies, cost-savings. Here in NSK bearing professional conservation work, there must be standard system processes, including running condition, lubricants, periodic removal, detection of noise, temperature, and so on.
Sense of bearing pressure into rotational flexibility should be no block. If there are clearly not flexible rotation, then axis dimensions are too big, the tolerance to cut. If the bearing onto the shaft by hand after turning there is a clear "rustle" sense, the tolerances of the shaft may be too large or the roundness of the shaft well. So you also control the shaft and housing tolerances you want to control the roundness.
First, the bearing is properly installed, directly related to precision, longevity, performance of the bearing. Installation and Design Department for bearing installation to fully research, analysis of bearing structures, and so on in order to ensure normal work of NSK bearings:
Cleaning bearings and bearing associated parts; this is important, note must be clean, preventing debris in it. Check the size and finishing of associated parts; this requires some specialized tools to ensure accuracy of bearing installation. Once the bearing is installed check; check whether the NSK bearing support, whether there is the wrong place. Supply of lubricants, required careful operation, was very important.
Second, bearing basic conditions for monitoring:
Need some professional, conducting regular inspections of NSK bearings, which can identify potential problems early will prevent unexpected machine abort, make production safe, increase factory productivity and efficiency. Bearings in use during the, often to monitor the bearings run basic external conditions such as temperature, vibration and noise measurement, and so on, so as to prevent.
Third, bearing tuneup, straightening:
These actions could accelerate fatigue and reduced bearing service life, can damage other parts of life. In addition, vibration and friction may increase significantly increased energy consumption and premature failure risk. However, in the bearing after installation, if not carefully tuned, straightening may lead to NSK bearings subjected to additional loads, friction and vibration. Which leads to premature damage of bearings in advance, so it should be a tuneup, straightening!
IV again, bearing lubrication:
If NSK bearings considering lubrication, oil lubrication of lubrication advantage. But grease lubrication around bearing structure can be simplified like that. In the course of operation, bearings require proper lubrication once again, lubricated bearing healthy running, in order for the bearing play function very well, first of all, to select the appropriate conditions of use, the use of the purpose of lubrication method, are lubricated with oil or grease lubrication is depends on the bearing of the case may be!
V, bearing removal:
To remove the tools with the appropriate, this will help prevent damage to the other machine components, does not correctly remove the technique may cause damage to the bearing, if when the life of NSK bearing reaches its final, it should be replaced. Although bearing can no longer be used, but correctly remove the bearings, replace new bearings in a timely manner, the new extension of the service life of the bearings can play a good role in promoting, so replacement of old and new, is very important, this needs professional personnel conduct inspections of operations
When bearings are mounted to the rotor dynamic balance easily produced when iron filings into the NSK bearing internal dynamic balance, so it is best to install NSK bearing dynamic balancing before. Some manufacturers for ease of Assembly, Assembly in the bearing room painted with some oil or grease lubrication effects, but in many cases the operator is difficult to control, if oil or grease in the bearing Interior accumulates more easily along the axis of rotation of the bearing into the bearing. Bearing it is best not to oil or grease, such as non-coating is not available to control shall not be bearing Interior accumulates.
