Of TIMKEN bearing equipment preventive maintenance, operation and peripheral parts replacement was removed when making an inspection, thrust ball bearing need to judge whether time bearing parts can be used again in turn and record the usage of good from bad. Carefully investigate and record the bearing and the appearance of being removed. In order to explore the residual amount of investigation and lubricant, after sampling, to clean the bearing well. Second check bearing raceway surface, rolling surface and cooperate with the surface condition and wear conditions of cage with and without damage to watch the race and abnormal situation especially the running track. Judge bearing can use again, and the extent of the damage to considering the thrust ball bearings, machine performance, importance, and operation conditions, such as inspection period to decide later. Test results, if found damage and bearing abnormal situation, please according to the bearing damage phenomenon to find out the reason, to develop countermeasures. In addition, the test results, there are some defects, if the TIMKEN bearing can't use, need to replace new bearing. At the time of anti friction bearing filling grease, may not need to use the theory of high pressure, unless very careful to use. High pressure can damage the bearing, waste grease, excessive grease caused by high temperature at risk and to cause bearing around invisible environment. In most applications, the ball or roller bearing lubrication, if grease level accounted for a third to a half of bearing capacity. Beyond the amount of usually will be sealed shell discharge and waste. 1, the installed on surface and the place has a requirement? If thrust ball bearing with iron filings, burr, dust and other foreign matter to enter, will make the bearing noise and vibration during operation, and even damage raceway and rolling body. So, before the installation of bearings, you must ensure that the installation surface and the environment clean. 2, bearing must be cleaned before installed? Bearing surface coated with anti-rust oil, you must use clean petrol or kerosene cleaning carefully, then coated with clean, high quality or high speed high temperature lubricating grease before installation. Cleanliness of TIMKEN bearing life and the influence of vibration noise is very big. But we especially want to remind you is: fully enclosed bearing not clean fuel. 3, how to select grease? Lubrication of the bearing work and life have very important influence. Here a brief introduction to select the general principles of the grease to you. Grease made out of base oil, thickener and additive, different types and different type of same kind grease properties vary widely, allowing the rotation of the limit, when the choice is important to note. The performance of the grease is mainly determined by the base oil. The basis of generally low viscosity oil is suitable for low temperature, high speed; High viscosity is suitable for high temperature, high load. Thickener and relationship with lubrication performance, thickening agent, water resistance to the water resistance of the grease. In principle, different brand of grease can't mix, and even the same thickening agent of grease, will also bring bad influence each other on the basis of different additives. 4, when lubricated bearing, oil paint, the more the better? Lubricated bearing, oil paint, the more the better, this is a common mistake. Thrust ball bearing and the bearing indoor excessive grease will cause excessive oil mixing, resulting in a high temperature. 5, how to install and disassemble? When installation do not directly face hammer thrust ball bearing and the bearing surface, should be to press, sleeve or other installation tools for uniform bearing force. If the installation surface coated with lubricating oil, will make the installation more smoothly. If the interference fit is larger, should put the bearing into the mineral oil heating to 90 ~ 100 ℃ in immediately after installation. When removing difficulties, it is recommended that you use disassembly tool to pull at the same time to careful labor the inner ring of hot oil, heat will make the TIMKEN bearing inner ring expansion, making it easier to fall off.
