Timken bearing equipment, regular maintenance, operation and external parts replacement, thrust ball bearings removed to check, in order to judge whether the sub-bearing parts can be used again and record usage in bad. Also carefully investigate and record split down the bearing and appearance. In order to clarify and investigate the remaining amount of lubricant, the sample after cleaning bearings.
Second, check the bearing raceway, the status of the rolling surface and the mating surface and cage wear state whether the injury and abnormalities, in particular to observe the trajectory of the raceway. Judgment bearing the possibility of re-use, and to consider the thrust ball bearing damage degree of machine performance, the importance of operating conditions, check the cycle, and then later decided.
Test results, bearing damage and abnormal situations, identify the reasons for the phenomenon by the bearing damage, and to develop countermeasures. In addition, test results, if the following defects,   Timken bearings can not be reused, new bearings need to be replaced.
Anti-friction bearing lubrication, you may need to use high-pressure theory, unless very carefully used. High pressure can damage bearings, waste grease, excessive grease caused by high temperature be dangerous and cause bearing around the invisible environment. In most applications, ball or roller bearings completely lubrication grease level bearing capacity of a third to half. The excess amount will usually be sealed shell discharge wasted.
1, on the mounting surface and installation site requirements?
If the thrust ball bearings, iron filings, burrs, dust and other foreign matter into the will bearing running noise and vibration, and even damage the raceway and rolling element. Therefore, before installing the bearing, you must make sure that the mounting surface and installation environment clean.
2, the bearings must be cleaned before installation?
Bearing surface is coated with anti-rust oil, you must be carefully cleaned with clean gasoline or kerosene, and then coated with a clean and high quality or high-speed high-temperature grease before installation.
Cleanliness timken bearing life and vibration noise is very large.
But we want to remind you: fully enclosed bearings do not have to clean fuel.
3, how to choose the grease?
Extremely important impact on the operation and life of the bearing lubrication.
Here to brief you select the general principles of the grease. Grease made of base oil, thickener and additives, grease performance of the different types and different brands of the same species vary greatly, the rotation limit allowed, the choice is important to note.
Grease performance is mainly determined by the base oil.
  Generally low-viscosity base oil suitable for low temperature, high-speed; high viscosity suitable for high temperature, high load.
The thickener related lubricating properties, water resistance of the thickener to determine the water resistance of the grease.
In principle, a different brand of grease can not be mixed, and even if the same kind of thickener of the grease will adversely affect each other additives different.
Lubricating bearings, grease coating the better?
Lubricated bearings, the grease coating as possible, which is a common misconception.
Thrust ball bearings and bearing indoor too much oil will cause excessive oil mixing, resulting in extremely high temperatures.
5, how to install and remove?
When installed directly hammering thrust ball bearing face and non-bearing surface, briquetting, sleeve, or other installation tool to make bearing uniform force.
If the mounting surface is coated with lubricating oil, will make installation more smoothly.
Such as interference with the larger bearing into the mineral oil, heated to 90 to 100 ° C immediately after installation. Demolition difficulties, it is recommended that you use the removal tool and pull outward to timken bearing inner ring, inner ring carefully poured hot oil, the heat will make swelling, making it easier to fall off.
