Because Timken imported bearings are high-precision products, improper assembly is easy to damage the bearing channel and lead to bearing damage. The bearing shall be equipped with a special mold during assembly, which cannot be knocked at will. When pressing the shaft, only the small ring can be stressed,
and when pressing the large ring, only the large ring can be stressed. Pneumatic or hydraulic pressure is required during assembly. During press assembly, the upper and lower molds shall be outside the horizontal state. If there is inclination, the bearing channel will be damaged due to stress and the bearing will make a guide sound.
When the bearing is installed on the rotor for dynamic balance, it is easy to put the iron filings generated during dynamic balance into the Timken inlet bearing, so it is Imported Bearing Grease necessary to perform dynamic balance before installing the bearing.
In order to facilitate assembly, some manufacturers apply some oil or grease in the bearing chamber for lubrication effect during assembly, but it is often difficult for operators to control the amount. If more oil or grease is accumulated in the bearing chamber, it is easy to enter the bearing along the shaft when the bearing rotates.
The bearing shall not be coated with oil or grease. If it must be coated, it shall be controlled and there shall Imported Bearing Grease be no accumulation in the bearing chamber.
The sound of the motor is very good during assembly, but after it is put in the warehouse for some time, the abnormal noise of the motor Imported Bearing Grease becomes very large, and there is serious rust when the bearing is removed. In the past, many manufacturers thought it was the bearing problem.
After our continuous publicity, now the motor factory has realized that the main problem is the insulating paint. This problem is mainly because the acidic substances volatilized from the insulating paint form corrosive substances at a certain temperature and humidity,
which corrodes the bearing channel and leads to the damage of Timken inlet bearing. The problem is that the insulation paint can only be Imported Bearing Grease Imported Bearing Grease used after drying for a period of time.
The service life of the bearing is closely related to manufacturing, assembly and use. It must be done well in each link in order to make Imported Bearing Grease the bearing in a good running state and prolong the service life of the bearing.
Drop several drops of oil on the filter paper and take a clean red filter paper. After the lubricating oil leaks, if there is black powder on the surface and there is a sense of astringency by hand, it indicates that there are many impurities in the lubricating oil. Good lubricating oil has no powder and feels dry, smooth and yellow.
Grease is very critical if using Timken imported bearings. The use of metamorphosed grease will not only fail to play its due role, but also damage the bearing.
① Oil flow observation method
Take two cups of lubricating oil to be checked. Put the other one on the table, lift the measuring cup Imported Bearing Grease filled with lubricating oil 30-40cm away from the table and tilt it, let the lubricating oil flow slowly into the empty cup, and observe its flow.
The lubricating oil with good quality should flow slender, uniform and continuous from time to time. If the oil flow is fast and slow, and Imported Bearing Grease sometimes large pieces flow down, it means that the lubricating oil has deteriorated.
② Hand twisting
A good lubricant feels lubricity, less wear debris and no friction. Twist the lubricant between thumb and index finger and grind it repeatedly.
If you feel a great sense of friction such as sand particles between your fingers, it indicates that there are many impurities in the Imported Bearing Grease lubricating oil and it cannot be used again. You should replace the lubricating oil with a new one.
③ Illumination method
Lift up the lubricating oil with a screwdriver on a sunny day. At an angle of 45 degrees to the horizontal. Observe the condition of oil drops according to the sunlight. Under the sunlight, it can be clearly seen that there is no wear debris in the lubricating oil. It can continue to function. If there are too many wear debris, replace the lubricating oil.
