Typically, temperature self-lubricating bearings with bearing operation began to rise slowly, 1-2 hours to stabilize. The normal temperature of the bearing due to the heat capacity of the machine, heat dissipation, speed and load another. If the lubrication, installation is not appropriate, the SKF bearings temperature can rise dramatically, and abnormal high temperature occurs, in which case you must stop and take the necessary precautions. Self-lubricating bearing temperature, generally by bearings outside of room temperature can be speculated that if oil hole can directly measure the temperature of bearing outer ring, is more appropriate.
High temperature often indicates that the bearing is in an abnormal situation. High temperatures may also be harmful to the bearing lubricant. Sometimes overheated bearing could be attributed to the bearing lubricant. Bearing temperature in more than 125 ° c long-term continuous transfers reduce the FAG bearings life. Cause of the high temperature bearings including: inadequate or excessive lubrication lubrication, lubricant. Contains impurities, excessive load, rings of bearing damage, inadequate clearance, and oil have high friction and so on.
Bearing temperature monitoring is necessary for continuity, whether measuring self-lubricating bearing itself or other important parts. If operating conditions do not change case, any temperature changes may have occurred at fault.
NSK bearings temperature measurement using a thermometer on a regular basis, such as digital thermometers for precision measurement of bearing temperature in Celsius or Fahrenheit temperature displays.
The importance of bearing, means when it is damaged, will cause the device to shut down, so this type of TIMKEN bearings better fitting a temperature probe.
Self-lubricating bearing in work, due to the effects of the external or internal factors, so that the original clearance changes, loss of precision, even causing "death" called clearance change failure. External factors such as the degree of interference is too large, the installation is not in place, expansion caused by temperature, instantaneous overload, intrinsic factors such as residual stress and residual austenite in clearance changes caused by instability, which is the main cause of failure.
First self-lubricating bearing dust the fan clean to avoid more dust into the bearings during installation
INA bearings seal sticker torn off, remove the card pins on shafts
Residual oil in the bearing with a clean tissue paper or a soft cloth to wipe clean, then wipe the shaft
Adding a little butter in the KOYO bearings, the principle is rather less not more so as not to seriously affect speed
Oil seal seal, with a little butter, and finally put the fans back into the video card
Plugged in try it, you'll find self-lubricating bearing fan's voice is much smaller, and then for 2 years at least. But need to be reminded that, although the voice was small, but due to limited precision by hand, the speed will drop slightly.
